Welcome the CML Product Catalogue. The Catalogue is a new style composite publication that brings together the former CML Product Selector and the CML Communications IC Selection Guide. This document supersedes both of those publications in their entirety. The advantage of having the two publications integrated as one is that it allows you to browse through CML’s product families at an introductory level, and to then explore individual products in more depth - all within the same document. Within the first part (Product Overviews) the descriptions at the start of each section summarise product families. Tables are included that offer a comparison within groups of devices with key performance figures and product benefits. Following the links in the tables will navigate you to more detailed information on individual devices in the relevant sections of the second part (Product Descriptions). CML’s products are listed in numerical sequence overleaf, followed by tables that allow you to search for suitable devices by application or function.

High performance digital radio systems are migrating towards the Software Defined Radio model, where a common hardware platform can be

used across a number of radio systems. System-specific operation and functions are fully software based within the DSP/microcontroller.

The world of the DSP and the microcontroller is a digital one, yet the real world, including RF, is analogue. Therefore, the important functions

sitting in front of the DSP are the analogue to digital converters and other auxiliary functions allowing the analogue world to interact with the digital

one.

The CMX983 AFE for Digital Radio bridges this gap between the DSP a digital radio’s RF section. Being flexible and high performance, this

device can form the basis of a digital radio platform. It provides direct connection to and support of the RF section along with a host of auxiliary

functions, effectively reducing the overall system size, cost and power consumption.

The CMX983 is suitable for radio systems employing modulation bandwidths up to 25.8kHz and is usable in satellite communication, high

performance wireless data and professional two-way radio systems.

The CMX983 provides a versatile interface to support a variety of transceiver architectures. The flexible nature of the main signal ADCs and

DACs makes the device suitable for a wide range of narrowband radio systems, supporting modulation bandwidths from 6 up to 25.8kHz.

Integrated auxiliary functions reduce PCB area with an ADC handling measurement of PA power and temperature, RSSI, battery and other

parameters whilst controlling trimming of TCXOs and other functions via low power DACs.

When coupled with other CML RF devices a highly integrated radio solution is possible, capable of supporting linear and constant envelope

modulations. All devices are compatible with a 3.3V digital I/O and are supported by a common C-BUS serial control channel simplifying radio

design.

The CMX991 is a single-chip, high performance, low cost RF transceiver that provides the core functions required to implement a full-featured radio transmitter and receiver. It operates from 100MHz to 1GHz and its I/Q architecture supports multiple modulation types and bandwidths with a single radio design. The half-duplex CMX991 integrates Tx modulators, Rx demodulators, IF PLL and IF VCO subsystems to minimise the external circuits needed when implementing a com-plete RF transceiver chip. User-selected modes suit different application requirements. The Tx path includes an I/Q modulator to accurately generate modulation at the IF fre-quency, which may then be translated to the final RF frequency by an integrated image-reject up-converter system.The I/Q modulator IF output is also made available for conversion to RF via external circuits, if desired. The Rx path includes an integrated 1st Rx mixer having two outputs to support two external 1st IF filter choices, then an integrated 2:1 input MUX followed by VGA and wideband signal level measurement functions, to support AGC implementation. The 1st IF signal is then either I/Q demodulated to Zero-IF or mixed to a Low IF output. The CMX991 provides differential and single-ended Rx output options and differential amplifiers for flexible signal conditioning.

Two separate, high performance, RF quadrature modulator ICs: the standard CMX993 and the wide bandwidth CMX993W product variant. The CMX993 and CMX993W are integrated, low voltage IQ modulator suitable for use in applications operating from 30MHz to 1000MHz. The device integrates two matched double-balanced mixers driven from a buffered and quadrature split local oscillator. The LO frequency is divided by either a factor of 2 or 4. The mixers form an I/Q vector modulator with programmable gain stages offering up to 30dB of gain control in 2.5dB steps. Uncommitted low frequency differential amplifiers are provided for users to configure. This may be used to implement functions such as filtering, differential to single ended signal conversion and level shifting. A digital control interface, C-BUS, (an SPI™ compatible interface) allows gain control as well as power management of individual internal blocks to optimize system perfor-mance. The C-BUS interface operates from its own supply domain enabling the device to be interfaced to different voltage baseband devices. The CMX993 and CMX993W devices are supplied in an RF optimized VQFN package.

Direct conversion receiver family with PowerTrade™ flexible power vs. performance modes CMX994 - Standard and low power modes CMX994A - Standard and additional low power modes CMX994E - Enhanced, standard and low power modes All three devices include a broadband LNA with gain control followed by a high dynamic range, very high IIP2, I/Q demodulator. The receiver baseband section includes amplifi-ers and precise, configurable bandwidth, baseband filter stages. LO generation is pro-vided by an integer-N PLL and a VCO negative resistance amplifier; an external LO may also be used. LO dividers are provided for flexible multi-band operation. The devices operate from a single 3.3V supply over a temperature range of –40°C to +85°C and are available in a small 40-pin VQFN (Q4) package. The CMX994A enables a significant reduction in power by allowing LO phase correction to be turned off. A further reduction is made possible by the facility to disable either the I or Q channel. The CMX994E expands on that by adding an enhanced performance mode that features improved intermodulation in the receive path mixers. Operate from a single 3.3V supply over a temperature range of –40°C to +85°C and are available in a small 40-pin VQFN (Q4) package.

The CMX264 is a frequency domain voice scrambler for use in analogue cellular phone systems, fixed and rolling code voice scrambler applications. It contains separate Tx and Rx paths for full duplex operation and operates under µProcessor control via a simple serial interface. In the Tx path, scrambling is achieved by splitting the audio band into two parts, or sub-bands, and frequency inverting each one. The frequency at which the signal is split, the "split-point", can be either fixed or rolling between four possible settings resulting in a transmitted audio signal which is unintelligi-ble to eavesdroppers. Descrambling is achieved by a receive device set to the same split point as the remote transmitter. Thus if the Tx and Rx devices are synchronously cycled through the same sequence of split points, a clear recovered signal will emerge at the output of the receiver A 4.433619MHz crystal is used allowing up to four split points to be programmed. The device is designed to be compatible with existing mobile and cell phone circuitry.

The CMX7031 and CMX7041 are half-duplex processor IC platforms built on FirmASIC®

technology that are suitable for use in multi-standard analogue Two-way Radio (TWR) systems. FirmASIC® component technology allows on-chip sub-systems to be reconfigured by a Function ImageTM (FI): this is a data file that is uploaded during device initialisation that defines the device's function and feature set. The CMX7031/CMX7041 enable a revolutionary new platform approach to radio design, enabling multi-mode analogue two-way radios to be developed based on a single radio platform, conforming to many systems: PMR, LMR, Trunking, Marine, Aviation, Amateur radio, NOAA weather radio and packet data radio. To enable full control of the radio functions and minimise the overall chip count, two user programmable system clock outputs are provides along with auxiliary ADC and DAC blocks. A user-programmable PLL, driven from the Xtal/reference clock input, gen-erates all internal clocks and allows one clock source to be internally reused for both baseband and RF synthesiser functions (for CMX7031 only). A flexible power control facility allows the device to maximise powersaving whilst not processing signals or when specific functions are not enabled. New Enhancements:

Marine DSC Expansion Sequences, enables precise position using marine DSC

Dual/Multi-mode Radios

The CMX7131 and CMX7141 are half-duplex processor IC platforms built on FirmASIC® tech-nology that are suitable for use in multi-standard digital PMR (DPMR) and dual-mode (analogue/digital) systems. FirmASIC® component technology allows on-chip sub-systems to be reconfigured by a Function Image™ (FI): this is a data file that is uploaded during device initialisation that defines the device's function and feature set. Dual mode and multi-mode digital PMR radios can now be developed based on a single radio platform conforming to a number of digital PMR systems/standards all with full analogue PMR backward compatibility. The Ultimate FDMA Digital Radio Chipset A number of the Function Images now support direct connection to CML’s CMX994 Di-rect Conversion Receiver. The combination of the CMX7131/7141 and CMX994 enables the highest integration, multi-standard FDMA digital/analogue PMR radio, to be realised. The CMX7131/7141 and CMX994 together address the market requirements for: Low power operation, small size, low cost, flexibility and high performance. Vocoder Support A number of Function Images manage voice and data systems autonomously with the CMX618 RALCWI (Robust Advanced Low Complexity Waveform Interpolation) Vocoder and third-party Vocoders. This minimises host microcontroller interactions enabling the lowest overall operating power and therefore the longest battery life for a digital PMR radio. Third–party Vocoders are also supported in a data transport mode of operation.

The CMX7131 and CMX7141 also include two auxiliary ADCs with four selectable inputs and four auxiliary DAC interfaces (with an optional RAMDAC on the first DAC output, to facilitate transmitter power ramping). Additionally the CMX7131 features two on-chip RF synthesisers, with easy Rx/Tx frequency changeover. The devices have flexible powersaving modes and each are available in both LQFP and VQFN packages. dPMR446 (Mode1/2) 7131/7141FI-1.x implements a half-duplex 4FSK modem and a large proportion of the dPMR Air Interface, Data Link and Call Control layers. In conjunction with a suitable host, Vocoder and RF section, a compact, low cost, low power digital PMR radio conforming to ETSI’s dPMR standard TS 102 490 can be realised. ARIB STD-T98 (DCR) 7131/7141FI-2.x implements a half-duplex 4FSK modem and a large proportion of the DCR Air Interface, Data Link and Call Control layers. In conjunction with a suitable host, Vocoder and RF section, a compact, low cost, low power dPMR radio conforming to ARIB STD- T98 Digital Convenience Radio stand-ard can be realised. NXDN™ 7131/7141FI-3.x implements the NXDN™ Air Interface Phyisical layer (layer 1), the Data Link layer (layer 2) plus a host of advance features in support of the overall radio. In conjunction with a suitable host controller, Vocoder and RF section, a compact, low cost, low power digital PMR radio conforming to the NXDN™ standard can be realised. dPMR446 (Mode1/2) and Analogue PMR 7131/7141FI-5.x provides a dPMR446 (Mode1/2) operation as defined in 7131/7141FI-1.x and a subset of Analogue PMR functions (Audio processing and sub-audio signalling) enabling dual mode analogue/digital operation without changing Function Image.

The CMX7861 'FirmCODEC'® is a full-featured analogue front end for DSP/Microcontroller based systems. The device is a combination of codec, embedded signal processing and auxiliary system support functions, allowing simple interfacing between analogue and digital systems. Single-ended and differential interface options are provided and I/Q-based operation is supported. The device can also be used in radio systems operating with channel band-widths up to 50kHz, interfacing RF devices to baseband DSP/microcontroller, perform-ing the main data conversion and auxiliary operations for monitoring and control. Fully-programmable, on-chip independent dual-channel digital channel filters can be utilised for signal conditioning purposes. An Intelligent four channel SAR, ADC, four independent DACs and GPIO sub-systems perform valuable functions and minimise host interaction and host I/O resources. Two synthesised system clock generators develop clock signals for off-chip use. The C-BUS/SPI master interface expands host C-BUS/SPI ports to control external devices. The CMX7861 utilises CML’s proprietary FirmASIC® component technology that ena-bles on-chip subsystems to be configured by a Function Image™ data file, which is uploaded during device initialisation and defines the device's function and feature set. The Function Image™ can be loaded automatically from a host microcontroller over the C-BUS serial interface or from an external memory device. The device's functions and features can be enhanced by subsequent Function Image™ releases, facilitating in-the-field upgrades. It is possible to design custom transmit filters for use when the CMX7861 is operating in Codec mode.

Audio Tone Signalling Applications

The CMX823 is a high performance, low power, audio tone decoder that can operate on low S/N signals. Each decoded tone frequency is user-defined to provide the flexibility to operate in a variety of paging, two-way radio and proprietary systems. Example systems and tones include: Motorola Quick Call series; GE groups A, B and Zetron, Reach and Plectron 2-tone radio paging; Motorola 5/6-tone paging; and the EIA, CCIR, ZVEI1 and EEA tonesets used for HSC radio paging and selcall. Up to 32 user-defined decode tone frequencies from 280Hz to 3500Hz are written to an internal RAM-based FIFO. (Two separate 32-tone FIFOs are provided and support fast switching between tone sets). Each programmed tone (entry in the list) is user-assigned to one of two (or both) tone groups. Two-tone sequence decoding is simplified by dynamically enabling one or the other tone group via a mode selection. The CMX823 asserts an interrupt on tone decoding state transitions, e.g. notone to decoded tone, decoded tone to notone, etc. STATUS and DECODED TONE PARAME-TERS Registers may then be read and indicate the decoder status, the target tone de-coded and its tone group.

FRS Text Messaging

CMX882 is a full-function half-duplex audio and signalling processor IC for FRS and PMR446 type facilities -for both complex and simple end-designs. Under the control of the host µC, all voiceband requirements are catered for: Voiceband and sub-audio filtering, pre/de-emphasis, compression and expansion, and audio routing and global level-setting with single or two-point modulation in the transmit path. The combination of new and standard signalling functions of this product offer, under software control, increased functionality, versatility and privacy. Standard Extended-Code CTCSS and DCS is integrated with the new XTCSS code implementation. XTCSS provides better squelch-centred privacy codes with the added advantage of ‘silent operation': no annoying interference from other sub-audio users. XTCSS fitted radios enjoy more privacy and flexibility of opera-tion. The CTCSS configuration of this product enables ‘Tone Cloning’. Additionally two unique features of this product are its CTCSS ‘All Call Code’ and ‘All Codes Monitor’ modes. XTCSS Signalling - A state-of-the art (squelch) signalling format, employing both sub-audio (CTCSS) and in-band (XTC) signalling concurrently, which offers more than twice as many privacy codes as standard CTCSS operation and completely eliminates interference caused by other traffic on the channel (quiet operation). Additionally the XTCSS signalling can be employed as on over-air control for such features as voice-scrambling and voice-compression. XTCSS is fully compatible with both conventional and enhanced CTCSS signal-ling operations and will implement the ‘All Call Code’ and ‘All Codes Monitor’ functions. Data for GPS The CMX882 facilitates Global Positioning by Satellite (GPS) by providing, in the Tx path, a 1200/2400 bps MSK data packet encoder (suitable for NMEA 0183 data transfer) incorporat-ing interleaving, FEC, CRC and data scrambling. In the Rx path a 1200/2400 bps data packet decoder with automatic bit-rate recognition, 16-bit frame-sync detector, error correction, data de-scrambling and packet disassembly is availa-ble. With ultra low power requirements and graduated powersave, this product only requires a smaller, lower-power µC than existing FRS/PMR446 solutions, is available in compact SSOP and TSSOP packages.

The CMX469A is a single-chip CMOS LSI circuit which operates as a full-duplex pin-selectable 1200, 2400 or 4800 baud FFSK Modem. The mark and space frequencies are 1200/1800, 1200/2400 and 2400/4800Hz respec-tively. Tone frequencies are phase continuous; transitions occur at the zero crossing point. Employing a common Xtal oscillator with a choice of two clock frequencies (1.008MHz or 4.032MHz) to provide baud-rate, transmit frequencies, and Rx and Tx synchronisa-tion, the transmitter and receiver operate entirely independently including individual section powersave functions. The CMX469A includes on-chip circuitry for Carrier Detect and Rx Clock recovery, both of which are made available as output pins. Rx, Tx and Carrier Detect paths each con-tain a bandpass filter to ensure the provision of optimum signal conditions both in the modem and for the Tx modulation circuitry. The CMX469A demonstrates a high sensitivity and good bit-error-rate under adverse signal conditions; the carrier detect time constant is set by an external capacitor, whose value should be arranged as required to further enhance this product’s performance in high noise environments. This low-power device requires few external components and is available in small out-line plastic SOIC and TSSOP packages.

The CMX589A is a single-chip full-duplex synchronous data pump/modem designed for Wireless Data Applications. Employing Gaussian filtering for Minimum Shift Keying (GMSK) baseband modulation applications, the CMX589A features a wide range of available data rates from 4000 to 200000 (200k) b/s. Data Rates and the choice of BT (0.3 or 0.5) are pin programmable to provide for differ-ent system requirements. The Tx and Rx digital data interfaces are bit serial, synchronized to generated Tx and Rx data clocks. Separate Tx and Rx Powersave inputs allow full or half-duplex opera-tion. Rx input levels can be set by suitable AC and DC level adjusting circuitry built with external components around an on-chip Rx Input Amplifier. Acquisition, Lock, and Hold of Rx data signals are made easier and faster by the use of Rx Control Inputs to clamp, detect, and/or hold input data levels and can be set by the µProcessor as required. The Rx S/N output provides an indication of the quality of the received signal.

The CMX7143 is a unique, highly-flexible single IC product offering wide-ranging wire-less data operations in one hardware package. This unique way of operating means that you can produce an individual end-product platform operable to (currently) three different schemes. A saving in time, cost and ma-terials. Built on CML’s proprietary FirmASIC technology, this IC can be configured by a Func-tion Image (FI) file to one of three individual functions: GMSK/GFSK Packet Data Modem 4FSK Packet Data Modem FFSK/MSK Modem Operation, in the host equipment, to alternative data schemes is achieved literally at the ‘press of a button’. FirmASIC IC function and configuration is achieved by the loading of a compact Func-tion Image file at start-up or when a change of data scheme is required. Function Image files, which are downloadable from the CML website, can be easily 'swopped' in the field by the host µC to allow the system to operate to an entirely differ-ent (data) scheme. The Function Image (FI) This device utilises CML’s proprietary FirmASIC component technology. On-chip sub-systems are configured by a Function Image: this is a data file that is up-loaded during device initialisation and defines the device's function and feature set.

Low Power Requirement with Powersave


Applications

Two-Way Paging Equipment

Mobile Data Systems

Wireless Telemetry

DataTAC Terminals

The CMX969 is a CMOS integrated circuit that contains all of the baseband signal processing and Medium Access Control (MAC) protocol functions required for a high performance DataTAC dual mode RD-LAP 19200bps and MDC 4800bps FSK Wireless Packet Data Modem suitable for use with the Motient/ARDIS network. It interfaces with the modem host processor and the radio modu-lation/demodulation circuits to deliver reliable two-way transfer of the application data over the wireless link. The CMX969 assembles application data received from the host processor, adds forward error correction (FEC) and error detection (CRC) information and interleaves the result for burst-error protection. After adding symbol and frame synchronisation codewords and channel status sym-bols, it converts the packet into a filtered analogue baseband signal for modulating the radio transmitter. In receive mode, the CMX969 performs the reverse function using the analogue baseband signals from the receiver frequency discriminator. After error correction and removal of the packet overhead, the recovered application data is supplied to the host processor. Any residual uncorrect-ed errors in the data will be flagged. A readout of the received signal quality is also provided. An optional Autonomous Frame Sync Detection function is provided for use in Motient/ARDIS systems employing Single Frequency Re-use operation. The CMX969 uses signal filtering, data block formats and FEC/CRC algorithms compatible with the MDC and RD-LAP over-air standards. The device is programmable to operate from a wide choice of Xtal frequencies and is available in 24 pin PDIP, SSOP and TSSOP packages.

The CMX990 provides, on-chip: a flexible, formattable GMSK packet and free-format modem, a dual synthesiser fed from an external source, IF and RF transceiver stages for both Rx and Tx modes, and auxiliary ADCs and DACs for system control and monitoring. Operating in the range of 400MHz to 1GHz at data rates of 4 to 16 kbps. This single-chip, half-duplex device requires a minimum of external components, keeping end-product board size, power consumption and cost to an absolute minimum. The versatile GMSK modem is configured for either packet and freeformat data operation via an efficient task-oriented Rx and Tx format and command structure combined with data scrambling, interleaving and FEC and CRC capabilities. Rx data acquisition, extraction and tracking functions use Rx data-quality feedback to support varying signal environments. IF and RF functions in the Tx path handle all the signal processing required to generate GMSK modulation within an offset phase locked loop. A simple external loop filter and VCO are all that are required to drive a power amplifier. In the Rx path, external circuits provide initial selectivity; the down conversion and IF processing are provided in the CMX990. An interface to an external IF filter is provided to allow selection of the appropriate channel bandwidth. System control and monitoring is comprehensively handled, internally and externally, via the 8-bit host interface, registers and on-chip ADCs and DACs.

The CMX909B is a half-duplex Gaussian Minimum Shift Keyed (GMSK) BT = 0.3 modem data pump with on-chip packet data handling. GMSK modulation optimises the data throughput for a given bandwidth RF channel and the on-chip packet data handling relieves the host µC of regular processing tasks, such as maintaining Bit and Frame Synchronisation, Block Formatting, CRC and FEC Error Pro-cessing, Data Interleaving and Scrambling. The demodulator uses decision feedback equalisation techniques to reduce the channel distortion effects and enhance the receiver performance without the computational over-head of maximum likelihood (Viterbi) estimation methods. The CMX909B is pin, function and software backwards compatible with the FX909A and MX909A modems and also uses the same external components. It offers improved performance, higher data rates and lower voltage operation, as well as handling the recent R14N extension to Mobitex for short block frames. The CMX909B also offers 2-strength Xtal driver circuitry – for wider choice of xtals, optional zero-error or one-error frame sync detection, multiple powersave options – for intelligent power management, and availability in 24-pin TSSOP, SSOP (low-height) and PDIP package options. The CMX909B is ideally suited to wireless data applications such as Mobitex terminals, wireless telemetry, licence-free radio data and ISM band radio schemes.

Interface

The FX/MX919B is a CMOS integrated circuit that contains all of the baseband signal processing and Medium Access Control (MAC) protocol functions required for a high performance half-duplex 4FSK Wireless Packet Data Modem. The FX/MX919B is backwards compatible with the FX/MX919A but offers better perfor-mance during radio link fading and selectable Tx symbol shapes. The FX/MX919B assembles application data received from the processor, adds forward error correction (FEC) and error detection (CRC) information and interleaves the result for burst-error protection. After adding symbol and frame synchronisation codewords, it converts the packet into a filtered 4-level analogue baseband signal for modulating the radio transmitter. In receive mode, the FX/MX919B performs the reverse function using the analogue baseband signals from the receiver discriminator. After error correction and removal of the packet overhead, the recovered application data is supplied to the processor. Any residual uncorrected errors in the data will be flagged. A readout of the SNR value during receipt of a packet is also provided. The FX/MX919B uses data block sizes and FEC/CRC algorithms suitable for applications which require the high-speed transfer of data over narrow-band wireless links. The device is programmable to operate at most standard bit-rates from a wide choice of Xtal/clock frequencies.

As a members of the CML DuraTALK® family of digital voice products, the CMX608/CMX618/CMX638 are flexible, high integration, high performance, RALCWI Vocoders, offering near toll-quality voice at very low bit rates.

CMX608: Half-duplex RALCWI Vocoder

CMX618: Half-duplex RALCWI Vocoder with Integrated Voice Codec

CMX638: Full-duplex RALCWI Vocoder with Integrated Voice Codec

A Forward Error Correction (FEC) engine provides optimum performance in real life applications. The RALCWI Vocoder comprises four independent functions which are selectable by the host: Voice Encoder, FEC Encoder, Voice Decoder and FEC Decoder. The CMX618 includes an integrated voice CODEC, offering a complete analogue voice to low bit rate vocoded data function, with integrated channel filters removing the need for external components, whereas the CMX608 requires an external voice CODEC. The devices all operate from a dual power supply (1.8V and 3.3V) and are available in both 48-pin LQFP (L4) and 48-pin VQFN (Q3) packages. In encode mode, the voice encoder uses a 20ms voice frame size with 2 programmable bit rates: 2400bps or 2750bps. The optional FEC encoder performs channel coding of the encoded voice (2400bps or 2750bps, depending on the selected mode) and forms an encoded, interleaved bit-stream of 3600bps (216 bits per 60ms packet or 288 bits per 80ms packet). In decode mode, the optional FEC decoder performs de-interleaving and channel de-coding of the coded bit-stream (216 bits per 60ms packet or 288 bits per 80ms packet) and forms an error-corrected bit-stream of encoded voice at 2400bps or 2750bps rate, depending on the selected mode. The FEC decoder can optionally use "soft decision" metrics to improve its decoding ability. The voice decoder then converts the error-corrected bit-stream back into a digit-ised voice signal. Soft Decision Decoding (SDD), Discontinuous Transmission detection (DTX), Voice Activity Detection (VAD) and Comfort Noise Generation (CNG) functions are also included, to further enhance the overall performance. Single (STD) and Dual (DTMF) Tones can be detected and sent separately in the coded

Digital Advantage for Analogue Radio

The CMX7011 is a flexible, half-duplex, digital voice encryption processor that provides the digital advantage to conventional analogue two-way radios. Digital voice scrambling is a key feature of the device, transmitting and receiving secure encrypted voice via an embedded robust data modem. The device allows simple implementation and configuration within existing designs and is intended to be added to a radio via an accessory module or "feature socket". The device is simple to control via a small, low-power microcontroller. The CMX7011 offers good quality speech which is better than that of traditional analogue radios at the fringes of reception and, using the internal digital encryption algorithm, signifi-cantly higher levels of security are achieved. Embedded within the CMX7011 is CML's proven and reliable RALCWI (Robust Advanced Low Complexity Waveform Interpolation) vocoder providing near toll quality speech at a low bit rate. A significant feature of the CMX7011 is the programmable push-to-talk (PTT) buffer which offers instant voice capture in transmit mode. The PTT buffer temporarily stores the initial part of the speech and can eliminate voice clipping caused by the time required to decode sub audio signals like CTCSS in the receiver, as well as to compensate for system delays caused by repeaters. Within the CMX7011's header frame is a user-programmable 8-bit address field which allows up to 256 individual user addresses to be defined. The device also offers a number of additional advanced features including Voice Storage and Retrieval, Secure Packet Data capability and Late/Re-entry protocol providing high performance in fading conditions. The CMX7011 uses CML's proprietary FirmASIC component technology, providing maximum flexibility with upgrade capability and a roadmap of future function enhancements. The CMX188 is a 'plug and play' (no Function Image upload required) version of the CMX7011. The CMX188 is pin and function compatible with the CMX7011 and is available for high quantity applications.

As a CML product built on FirmASIC® technology, these highly integrated ICs can be configured, by Function Image™ file to one of two separate AIS functions: • Marine AIS Class B (Tx/Rx) • Marine AIS Rx-only Marine AIS Class B Implementation - Function Image™ 7032/7042FI-1.x The 7032/7042FI-1.x provides a half-duplex, marine AIS baseband signalling processor IC with two on-chip RF synthesisers additionally available on the CMX7032. Comprising two parallel limiter-discriminator Rx paths and one I and Q or two-point modulation Tx output path, the CMX7032 and the CMX7042 fulfil the requirements of the Class B marine AIS system. Each of these paths is configurable for marine AIS or DSC operation. Marine AIS Rx-only Implementation - Function Image™ 7032FI-2.x A marine AIS baseband signalling processor IC, the CMX7032FI-2.x fulfils the require-ments of the Rx-only marine AIS receiver market. The 7032/7042FI-2.x comprises two parallel Limiter-Discriminator Rx paths and an RS232 style/NMEA 0183-HS compatible output (38400 baud). The device performs signal demodulation with associated marine AIS functions, such as training sequence detection, NRZI conversion and HDLC processing (flags, bit de-stuffing, CRC check). Integrated Rx data buffers are also provided which removes the need for a host IC. Provision of a number of user-programmable areas within the FI allows the RF synthe-sisers of the CMX7032 to be programmed directly, which simplifies the system hard-ware design, reducing the overall equipment cost and size. Allowance is made in the RS232 interface for an external GPS device to be connected to reduce the proliferation of interface connections in the final product design.

Designed specifically for all current modes of AIS operation, the CMX910 offers a highly integrated IC capable of performing all of the required data-handling and formatting, timing, distribution and control functions under the control of the host. Provided on-chip are both of the mandated GF(M)SK Rx channels and a single Tx channel. Selectable to 12.5 and 25 kHz modes for marine AIS, the CMX910 accommodates, in Rx and Tx, both full AIS data packet assembly and dissassembly and a basic ‘raw’ data facility. Both marine AIS (G(M)FSK) and DSC (FSK) I/Q modulated signalling modes are available. Integration of all marine AIS functions, including versatile synchronisation and timing and control facilities are available on this single compact IC. Control and interfacing, including upgraded ‘data-streaming’, are via the CML C-BUS serial interface, with a host-controlled expansion port for the addition of other CML (or other) ICs. A third, parallel (Rx) decode path, accommodates the additional DSC (FSK) signalling from an external modem for Class A marine AIS applications. With its high integration on-chip of marine AIS-specific functions and wide-ranging data-signal processing capabilities, the CMX910 reduces the final-product board-area require-ment and component count whilst drastically reducing the host µC load by minimising the software generation effort; all with a view to an accelerated time-to-market. The provision of the C-BUS expansion port, an RF device enabling port and a number of auxiliary ADCs and DACs, simplifies the system hardware implementation, further reducing the overall equipment cost and size.

The CMX605 is an integrated telecom tone generator and DTMF encoder/decoder (codec) designed for ISDN interfaces, Wireless Local Loop and Analogue-to-Digital Phone Conversion systems. The tone generator covers an extensive range of pre-programmed tones used in ana-logue phone systems (POTS). Three outputs are provided: ‘Ringing signals’, ‘In-band tones or FSK data’, and ‘12kHz/16kHz Metering pulses’. Simple software control facilitates the interface to a wide range of commonly used µCs and SLICs, enabling a comprehensive analogue telephone line presentation. The DTMF encoder/decoder presents the digital line interface with DTMF dialling infor-mation received from the telephone user and generates the appropriate DTMF tones for the POTS interface. DTMF tone pairs can be encoded along with each tone singly or with other dual tone signals, such as those used in CIDCW systems and ‘On Hook’ signalling systems. Other tone standards supported are: Fax and Modem ‘answer’ and ‘originate’, ITU (CCITT) ‘R1’ and ‘R2’ signals, and sufficient tones for simple melody generation. Com-munication to and from the host µController is performed by a ‘C-BUS’ serial interface, which is compatible with the ‘SPI’ interface.

The CMX641A is a low power, system selectable Dual Subscriber Pulse Metering (SPM) Detector – two detectors on a single chip – to indicate the presence on a telephone line of either 12kHz or 16kHz telephone call charge frequencies. The detection sensitivity, frequency and bandwidth are independently selectable for each channel, under µC control, as is the frequency of the security tone generator, which may be ASK modulated by an external signal. The CMX641A is also backwards compatible with the FX641 and MX641 dual SPM detectors, whilst offering a lower operating voltage and power requirement. The CMX641A has two modes of operation: 1. Fixed Bandwidth Operating state, in which the two channels are set to the same system frequency and sensitivity setting. Sensitivity and system frequency can be under either µC or external control. This state is fully pin and function compatible with the FX641 and MX641. 2. Enhanced Features Operating state, under µC control, in which each channel has inde-pendently controllable sensitivity, bandwidth and system frequency (12kHz or 16kHz). There is also a 12kHz/16kHz transmission tone which can be keyed on and off directly by a dedicated logic pin. This device is suitable for PBX/PABX line-card installations, payphone security applica-tions and pair-gain systems. The CMX641A is available in SOIC package and consumes typically 1.2mA at 3V.

The CMX673 is a general purpose call progress tone detector for use in Public Switched Telephone System (PSTN) applications. Call progress detection allows equipment which dials into the PSTN network to monitor the progress of the resulting call: Ringing, Busy, Not Available and Answer states can be determined. The CMX673 uses advanced digital signal processing techniques to detect tones in the frequency band 315 to 650 Hz. The use of DSP techniques allows the CMX673 to distinguish between valid call progress tone signals and line noise or voice, low false detection rates result. This is in contrast to other call progress detection devices which are based on simple filtering techniques. The detection timing of the CMX673 allows it to operate with almost any call progress system. In particular the ‘stuttered dial tone’ of voice mail messaging systems is supported. The use of digital processing and small geometry CMOS design techniques allows the CMX673 to offer a complete call progress detector which analyses both frequency and amplitude in a single 8 pin (PDIP) package. This, coupled with industry-leading performance and substantially lower power supply requirements than comparable devices, demonstrates CML’s unique capability in this area.

The CMX683 is a general purpose Call Progress tone detector for use in monitoring the progress of calls in Public Switched Telephone System (PSTN) applications. Dial Tone, Ringing, Busy and Not Available states can be distinguished by using the host µC to qualify the cadence of the CP DETECT output. The CMX683 uses advanced digital techniques to characterise valid Call Progress tones, unwanted tones, line noise and voice or music signals. In contrast, to Call Pro-gress detection devices based on simple filtering techniques, the CMX683 offers excellent sensitivity coupled with low false detection rates. The response time of the CMX683 allows it to operate with almost any Call Progress system. In particular the ‘stuttered dial tone’ of voice mail messaging systems is supported. The use of statistical processing techniques, which analyse signal frequency, duration and amplitude, enable the CMX683 to distinguish voice or music activity from DTMF or Call Progress signals. Separate outputs integrate the "voice" activity over both shorter and longer periods, enabling payphone and other billing systems to commence charging when a line con-nection has been established. A single 3.58MHz crystal ensures accurate and repeatable performance. With supply requirements between 2.7V and 5.5V and a low current consumption, the CMX683 can be easily integrated into a wide range of telecom equipments. The CMX683 has a similar pinout to all commonly used Call Progress detectors and is available in DIP, TSSOP and SOIC packages.

The CMX850 combines a dual-port V.22bis modem with an 8051 microcontroller including 8k of RAM to form a powerful communications processor. Extended addressing offers page-mode access to 4Mbytes of external FLASH memory. The 8051 runs from the ~12MHz oscillator with a choice of sub-multiple frequencies down to ~12kHz giving a range of low power operating modes. The supply voltage is in the range: 3.0 to 3.6 V. A Watchdog Timer and standard 8051 Timers are included. I/O facilities include an LCD controller interface, 8x16 keypad inter-face with interrupts, a UART, two low-power PWM outputs, and a multiplexed 2-input 10-bit A-to-D converter. Unused functions can be alternatively used as GPIO. Low power and very low power (sleep) modes contribute to low battery consumption. The MUXAD pin allows the 8051 to multiplex the eight lower address and data bus lines to release further pins for I/O (debug support etc.). The V.22bis modem can be woken from sleep mode by ‘ringing’ or ‘line-reversals’. The CMX850 is an extremely compact and low-power microcircuit that will satisfy all of the communications, control, data and signalling requirements of any wireline end-product using on-line communication.

The CMX860 is a flexible, low-power Telephone Signalling Transceiver IC, designed for use in a wide range of line-powered telephone equipment. The IC combines the functions of a DTMF encoder and decoder, V.23 and Bell 202 modulator and demodulator plus call progress circuitry with analogue switching between line and phone interfaces. Ring detection, local phone off-hook detection and a relay driver for line hook-switch operation are also provided under the control of 'C-BUS'. The ring and hook detectors operate whilst the remainder of the IC is powersaved, generating an interrupt to wake-up the host µC when further processing or signalling is required. All on-chip functions and switching arrangements are controlled via the C-BUS command/data serial bus. The CMX860 is designed to operate at 2.7V and utilises CML’s low power DTMF decoder and V.23 modem technology.

The CMX866 is a multi-standard modem for use in telephone based information and telemetry systems. Control of the device is via AT commands over a simple 9600bps serial interface, compatible with most types of host µController. An RS232 compatible interface can be created by the addition of a Level Converter. The data transmitted and received by the modem is also transferred over the same serial interface. The on-chip µController interprets these AT commands and controls an internal DSP, which provides the modem and anciliary functions such as Ring Detection, Call Progress Detection, Hook Switch control and DTMF autodialling. User-specific DSP functions are also available via the AT command set. Hardware support is provided for V.23 and Bell 202 Fast Turnaround and for rapid return to AT Command mode. A Fast Connect mode hasm been implemented to reduce modem connection time. Flexible line driver and receive hybrid circuits are integrated on chip, requiring only passive external components to build a 2 or 4-wire line interface. Complete examples of 2-wire line interfaces to an external host µC and to an RS232 interface, including the additional components required for Type 1 CLI, are provided. The device features a Hook Switch relay drive output and a Ring Detector circuit that remain operational when the CMX866 is in ‘Zero-Power’ or Powersave mode, providing an interrupt which can be used to wake up an external host µC, as well as the CMX866, when line voltage reversal or ringing is detected.

The CMX869B is a multi-standard modem for use in EPOS terminals and telephone based information and telemetry systems. This highly integrated single-chip modem IC provides the functions needed to construct a ITU V.32 bis automode modem or a V.22 bis, V.22, V.21 and Bell 202, Bell 103 compatible modem operating under the control of external host timing for EPOS and other proprietary protocols. The V.32 bis automode-modem provides operation from 14400 bps with automatic fallback through to 4800 bps, retrain, rate re-negotiation and automatic detection of V.22 and V.22 bis modems. A high-quality DTMF decoder with excellent immunity to falsing on voice and a standard DTMF encoder are included. Alternatively, the device can transmit and detect user-programmed single and dual-tone signals, call progress signals or modem calling and answering tones. The CMX869B features a software controlled output to drive a hook switch relay and a ring detector block that continues to function when the device is in Powersave mode. When a line voltage reversal or ringing signal is detected, the ring detector circuit provides an interrupt that can wake up the host µController. Line input and line outputs can be single-ended or differential and the line-output amplifier is capable of directly driving into a low-impedance transformer or opto-isolated DAA. The hybrid and gain control circuits are integrated on chip, requiring only passive external components to build a 2- or 4-wire line interface. Host control and data transfer is via a simple, high-speed serial bus that operates in normal and Powersave modes and which is compatible with popular µC serial interfaces. An embedded USART accepts multi-format asynchronous data with V.14 support, or allows unformatted synchronous data or HDLC framed data to be received or transmitted. Data transfer can be in either an 8- or 16-bit format.
