1-3. Circuit Description

1. CMOS Block System

BI-202/203/204 BoardThe BI-202, BI-203 and BI-204 boards are the rigidflexible boards connecting the CMOS image sensors (IC1)to the DPR-289A board.

The CMOS image sensor receives the three primary colorsof R, G and B that are separated from the incoming lightby the prism. The CMOS image sensor converts theincoming primary color to electric signal. The built-in 12-bit column A/D converters then convert the R, G and Banalog video signals to the digital video signals respective-ly.The electronic shutter, analog gain amplifier and blacklevel clamp functions are also provided in the aboveboards.

The BI-202 board is for the R-channel signal, the BI -203board is for the G-channel signal and the BI -204 board isfor the B-channel signal.The CMOS image sensor receives the sync signal and theserial communication signal from the DPR-289A board.The 12-bit digital video signals that are supplied from theCMOS image sensors pass through the EMI filters (FL1 toFL4) and are input to the DPR-289A board.Various decoupling capacitors and the damping resistorsare also mounted in the above boards.IC3 of the BI-203 board is a temperature sensor that sendsthe temperature data to the CAMERA MICON (camera u-processor: IC314) on the DPR-289A board via I2C bus.

2. Camera Block System

DPR-289A BoardThe DPR-289A board consists of the Camera SignalProcessor IC (IC100) and the CAMERA MICON (camerau-processor: IC314) whereas the Camera Signal ProcessorIC (IC100) performs various processing on the digitalvideo signal supplied from the CMOS image sensor, andthe CAMERA MICON (IC314) performs control of IC100and other various controls such as control of the CMOSimage sensor and of lens. The output digital video (Y/C)signal is sent to the next circuit the video (baseband video)signal processing circuit.

The 12-bit digital video (RGB) signals supplied from theCMOS block (BI-202, BI-203 and BI-204 boards) firstenter the camera signal processor IC (IC100). In thecamera signal processor IC (IC100), average value, peakvalue of the RGB digital video signals that are required for

the following AUTO operations of the camera are detected.The detected signals are sent to the CAMERA MICON(camera u-processor: IC314).. Auto white balance. Auto black balance. Auto focus. Auto iris. Auto knee

The digital video signal from the CMOS image sensorenters first the selector circuit selecting either the digitalvideo signal from the CMOS image sensor or the internalTEST signal. The output video signal from the selectorenters the compensation circuits consisting of the CMOSimager-related compensation circuit and the lens-relatedcompensation circuit. The video signal then receives thewhite balance processing, and the matrix signal and thedetail signal are added to the video signal. The video signalthen receives the pedestal control, knee compensation,gamma correction and white/black clip processing. Thevideo signal finally enters the baseband processing IC(IC400).The pixel number conversion processing from 1920/1080to 1440/1080 or 1280/720 is also performed inside IC100.

The CAMERA MICON (camera u-processor: IC314)performs the overall control over the entire camera systemand is controlled by the camera system controller(IC1600).Peripheral ICs of the CAMERA MICON (camera u-processor: IC314) are FLAH ROM (IC312) and SRAM(IC313). The CAMERA MICON (camera processor:IC314) confirms the iris control and lens setup when theanalog I/F lens is installed.

3. Video Signal System

DPR-289A BoardThe digital video (Y/C) signal output from the camerasignal processor IC (IC100) enters the baseband processingIC (IC400).The baseband processing IC (IC400) performs the overallbaseband processing of video and audio signals with asingle chip IC containing the various scaler functions(supporting the multiple format outputs), various OSDfunctions, PLL function (54 MHz 74 MHz) and CPU.The baseband processing IC (IC400) provides the follow-ing outputs:. HD/SD-SDI (digital): To TX-129 board. HD/SD Component (analog): To JK-81 board. Composite (analog): To JK-84 board. S-Video (analog): To JK-84 board. LCD signal (digital): To IF-1072 board

1-6 PMW-EX3

The input/output signals of the baseband processing IC(IC400) are the following signals:. MPEG encoder/decoder I/F signal (digital): To IC901. Audio I/F signal (digital): To IC804PAM memory (IC700, IC701).Peripheral circuits of the built-in CPU are FLASH ROM(IC603) and SDRAM (IC607).The baseband processing IC (IC400) is controlled by thesystem controller (IC1600). The LCD driver IC, SDI Co-pro, the audio system and the power save control of theoutput systems are controlled by the built-in CPU insideIC400.

4. Media Recording and Playback

DPR-289A boardOutput from the baseband processing IC (IC400) is inputinto the MPEG encoder/decoder (IC901).The MPEG encoder/decoder (IC901) is the single-chipMPEG Codec IC that encodes and decodes both the high-quality HD video signal and audio signal in real-time. Ithas various interfaces with signals such as MPEG video,video input/output, MPEG audio, audio input/output, bitstream input/output, and interface with the host.IC901 output is then input into LSI (IC900) for AVITsignal processing.LSI (IC900) for AVIT signal processing contains the built-in CPU and has interfaces for DDR2 SDRAM memory(IC1000, IC1001), PCI bus, PCI-Express bus, I/O forIC901, and serial communication with system controller(IC1600).IC900 is also connected to the NOR-type Flash ROM(IC1100) to read the CPU program in the IC900 duringinitial startup.LSI (IC900) for AVIT signal processing is controlled bythe system controller (IC1600), in the same way as othermain devices, and provides the following types of func-tions: video/audio stream control, access to the SxSmemory card, mass storage operations when connected toUSB and HDV device controls when connected to i-LINK.

Explanation of peripheral devices

Two memory card slot boards (EC-63) are connected to thedual channel PCI-Express signals coming from IC900through a 0.5 mm pitch, 30-pin fine coaxial cables con-nected to CN1300 and CN1301.Furthermore, dual channel USB host signals output fromUSB host controller (IC1302) are connect to the EC-63board through fine coaxial cables just as with the PCI-Express signals.IC1302 is controlled by PCI bus from IC900.

USB device signal output from USB device controller(IC1101) is connected to output board (JK-81) through theboth-sided flexible board (HN-347) from CN1805 connec-tor, and then it is connected to USB Mini-B connector(CN6) on the JK-81 board.IC1101 is controlled by the dedicated bus from IC900.If there is no USB connection, the power supply forIC1101 drops off.

The i-Link signal output from the i-Link controller(IC1200) passes through the both-sided flexible board(HN-337) from the CN1803 connector. Then, the signal issent from CN3 on HN-337 to the i-Link connector board(CN-3050) through the shielded wire, and connected to the4 Pin i-Link connector (CN3) on the CN-3050 board.IC1200 is controlled by the PCI bus from IC900.

Fig. 1. Audio block diagram

. Audio signal from the built-in microphone on the MA-164 board is input to the balanced input amplifier IC101and IC201 of this board. Output of the balanced amplifi-er is connected to the analog switch (IC105, IC205) forswitching between [INT/EXT].

. The DC-DC converter (IC1, Q1) for microphone power+48 V is built-in, and when EXT MIC +48 V is going tobe supplied, the EXT MIC +48 V is supplied by theswitch (Q301, Q302, Q321 and Q322).

. The audio input signals from MIC and LINE are input toa common circuit that receives both of the MIC inputlevel (_8 dBu to _65 dBu) and the LINE input level (+4dBu). The input attenuator is inserted in the circuitswitch (Q103 to Q105, Q203 to Q205) as required. Thisaudio input signal is received by the balanced inputamplifier (IC102, IC202) that performs amplification of0/+12 dB and switching (Q110, Q111, Q210, Q211) inaccordance with the level that is set by INPUT TRIM.After that, the audio signal is connected to the [INT/EXT] switch (IC105, IC205).

. The [INT/EXT] switch (IC105, IC205) performs not onlythe INT/EXT switching but also performs the inputchannel mode selection [CH1/ (CH1/CH2)].

. SEL/AMP (1, 2) is a signal selector and buffer amplifierto perform AGC link.

. Serial controlThe I2C control signal from Display Block (Base band)is converted into GPI, and performs switching such as[INT/EXT], [LINE/MIC/MIC+48], [CH1/ (CH/CH)],and AGC [Linked/Separated] for CH1 and CH2.

DPR-289A board (Audio block)The AU-318 board is comprised of two pieces of theAudio Codec IC and the C-PLD.

. Audio Codec (IC800, IC801)The analog audio signal from the AU-318 board isconnected to IC800 and IC801 that are the Audio Codec(PGA, ADC, DSP, Digital IF, headphones amplifier,speaker amplifier are built on one chip and the parame-ters are set with I2C).The Input TRIM (PGA) functions in the [MANUAL]mode, and AGC functions in the [AUTO] mode tocontrol the audio signal level. The analog signal after

1-8 PMW-EX3

level adjustment is converted to the digital signal withthe ADC.The digital signal receives the audio level controlprocessing from the DSP. After the audio signal receivesthe [Wind Filter] (on/off) processing, the digital signal isoutput for audio recording.Playback output (including EE) is the digital signal thatis connected to Audio Codec where it is converted to theanalog signal with DAC and output to the ASW-66board.Furthermore, the audio signal that is processed for audiomonitoring in the ASW-66 board is connected to theheadphones amplifier and speaker amplifier through themonitor level control from the AUX input of IC800.

. C-PLD (IC804)After the digital signal output signal from the AudioCodec is amplified by +12 dB, it is supplied to theDisplay Block (Base band). C-PLD (IC804) also re-ceives the playback output signal from the DisplayBlock.The playback system selects CH1/CH2 or CH3/CH4,connects EE, and connects TEST TONE from theDisplay Block depending on the data.Furthermore, C-PLD divides the clock signal that issupplied from the Display Block to Audio Codec.

. Serial controlThe I2C control from Display Block (Base band) selectseither IC800 or IC801 for the target with I2C MPX andsets the register of IC800 or IC801.

HN-337 flexible boardIt relays the audio signal from the DPR-289A board to theASW-66 board.

ASW-66 board (Audio block). Analog output from the DPR-289A board Audio Codec

is buffered by IC103 and is output to the A/V connectorafter passing through the audio MUTE control.

. Analog output from DAC on the DPR-289A board re-enters into the AUX input of the DPR-289A boardAUDIO CODEC after passing through the monitorselector/mixer (IC100, IC101, IC102), and becomes themonitor signal.

. Serial controlI2C control signal from Display Block (Base band) isoutput at GPI, and performs the switching betweenMONITOR [CH1/CH2] / [CH1+CH2] / [CH1] / [CH2]for CH1 and CH2 respectively, and at the same timecontrols the BEEP on/off.

JK-84 board (Audio block)This is the connector board. The audio output from theASW-66 board is connected to RCA PIN connector.

It operates on a 27 MHz clock (X1600).FLASH ROM (IC1603), SDRAM (IC1604), and EE-PROM (IC1703) are mounted as the peripheral ICs.It performs the system control through serial communica-tion with IC314 of the camera block system, IC400 of thevideo signal system, and IC900 of the media recording/playback system.

PMW-EX3 1-9

Main functions of the system controller andperipherals(1) Reading operation switch information

Reading the switch information and the LED controlare performed by I2C bus communication with eachsub-microprocessor.. Handle switch: IC100 on the KSW-54 board. Inside panel front switch: IC601 on the SWC-48

board. Rear panel switch: IC106 on the ASW-66 board. Power supply switch: IC1001 on the RE-261 board

(2) Watch IC (RTC) controlThe watch IC (IC50) is built onto the AU-318 board.The watch IC (IC50) is backed up by a lithium coinbattery, and the current time is read or set via IC601 on theSWC-48 board.

(3) Infrared remote control demodulationThe RM-214 board has an IC (IC1) for infrared remotecontrol signal demodulation, and it receives the commandcodes via IC100 on the KSW-54 board.

(4) Info-Battery communicationThe Info-Battery of SM bus specifications is supported.The serial terminal of the battery connector is connected toIC1001 on the RE-261 board. This IC1001 reads thebattery authentication, battery type, remaining power, andother information and send them to the system controllervia I2C bus communication.

(5) Power supply voltage detectionThe power supply voltage at the DC IN connector ismeasured by the A/D port on IC1001 on the RE-261 board,and it is posted to the system controller as the input voltagevalue.

(6) Power system controlIC1001 on the RE-261 board checks that the power switchon the PMW-EX3 is turned ON, and turns on the systemcontroller of IC1600. After that, it controls the power foreach circuit block according to the system controller.The system controller controls the respective power supplysystems in the RE-260 and RE-261 boards according to theoperation mode of the device, via the power supply u-processor on the RE-261 board.By turning off the power systems to unnecessary circuitsblocks, power can be saved.

(7) 700P communicationThe serial communication driver (IC803) is mounted onthe TX-129 board.Serial communication with the remote control unit con-nected to the REMOTE connector is performed.

7. SDI/GENLOCK/TC IN/TC OUT

TX-129 board(1) SDI outputThis board receives the parallel video signal with FPGA(IC100) and IC500 and outputs the SDI signal.Furthermore, it performs audio or timecode embedding.The video and audio signals are supplied from CN400 onthe DPR-289A board to CN100 on the TX-129 board witha 0.4 mm pitch, 40-pin fine coaxial cable.The power voltages are supplied from CN401 on the DPR-289A board to CN700 on the TX-129 board with a 15-pinharness.Output SDI signals are supplied to CN500.Output SDI signals are then supplied from CN500 to thecoaxial connector via the mini coaxial connector and minicoaxial cable.The PLL circuit is used to reduce jitter of the HD-SDIclock signal.The FPGA (IC100) is controlled by IC400 on the DPR-289A board through 4-line serial communication.The FPGA program is stored in the IC203 ROM, andJTAG can be used to overwrite the data from IC1600 onthe DPR-289A board.When not using SDI, the power to cable driver insideIC500 is turned off.

(2) GENLOCKIn IC902, sync signal separation is performed for GNE-LOCK. The separated sync signal enters IC400 on theDPR-289A board where phase is compared by the internalcounter of IC400 and by IC521 to control the VCXO(X500).

(3) TC IN/TC OUTIC900, IC901, and IC907 reshape the waveform of thetime code connected to the TC IN connector and input it toIC100.IC903 is the external output circuit for the time code OUTsignal, which outputs the signal to the TC OUT connector.They communicate with the FPGA (IC100) through the 4-line serial interface on the DPR-289A board.

1-10 PMW-EX3

. Power supply reverse connection protectionIf the input power has reverse voltage, Q301 on the RE-260 board is immediately turned off and UNREG poweris stopped on the GND side, and the protection functionworks.

(2) DC/DC converter functionThe power supply output is divided into 25 systems, whichare separated into four blocks as seen below.

. CMOS/camera block system, 7 systems(+4.6 V, +3.1 V, UNREG, etc.)

. Audio/video signal system, 7 systems(+13.5 V, _4.6 V, +4.6 V, etc.)

. System controller system, 5 systems(+4.6 V, +3.1 V, +2.5 V, etc.)

. Media recording/playback system, 6 systems(+3.1 V, +2.5 V, +1.8 V, etc.)

The sequence control (powering up and powering down)for the power supply system is controlled by the POW-ER SUPPLY MICON (power supply u-processor:IC1001) for the respective power supply blocks of eachblock.By turning off the power for each block according to theoperation mode (camera mode or media mode), theoptimal power consumption for each operation isachieved.

. Short-circuit protection for each power supply systemThe circuit settings monitor each output voltage orcurrent for each power supply system and operate theprotection circuits per block.Even after the protection circuit is cleared, automaticrecovery is not performed and the power must be turnedon again.Even after short-circuit is cleared, the protection circuitdoes not recover automatically and the power must beturned on again.

Battery information functions. Battery authentication function

The authentication function checks whether the battery isof the specified type. This helps prevent one cause ofmajor accidents when using batteries as a power supply.If the attached batter is not the specified type of batter,the camera immediately turns off.

. Battery Info functionIn an intelligent (specified) battery, the battery canmonitor information, such as how many times the batteryhas been recycled or the internal temperature for thebattery. This helps provide detailed information aboutthe battery, including whether the battery is damaged orhow long the life is, in order to provide optimal operations.

8. Power supply system

RE-260/261 boardThis board is comprised of the power supply circuit andthe POWER SUPPLY MICON (power supply u-processor:IC1001 on the RE-261 board).However, part of the low-voltage power supply is mountedon the DPR-289A board.

(1) Input power supply (UNREG) system operationsWhen the UNREG power is input, the EVER power stateis established.In this state, the ON/OFF state of the Power switch can berecognized.If the POWER SUPPLY MICON (power supply u-processor: IC1001) recognizes that Power switch is ON,the power is turned on for the system control system andthe POWER SUPPLY MICON (power supply u-processor:IC1001) controls the power supply for each block accord-ing to the system controller (DPR-289A board: IC1600).The normal value for the input power supply (UNREG) isin the range of about +10.5 V to +18 V.

. Battery/EXT-DC selectInput power comes in two systems: Battery and EXT-DC. This switch monitors the input voltage for eachinput and automatically switches the circuit settings withpriority given to EXT-DC.

. Input overvoltage protectionIf the voltage is too high in the UNREG power supply,the overvoltage protection circuit starts operating aroundthe set value of +17.9 V, and the camera shuts down.When the input power supply voltage to this circuitbecomes less than +17.9 V, the power supply immedi-ately switches on with automatic recovery.

. Input low-voltage protectionIf the voltage is too low in the UNREG power supply,the low-voltage protection circuit starts operating aroundthe set value of +10.5 V according to the control by thePOWER SUPPLY MICON (power supply u-processor:IC1001), and the camera shuts down. When the inputpower supply voltage becomes higher than +10.5 V, thepower supply immediately switches on with automaticrecovery according to the control by the POWERSUPPLY MICON (power supply u-processor: IC1001).

. Overcurrent detectionThe overcurrent detection circuit is comprised of IC308on the RE-260 board. The setting value is approximately4.3 (A). Even after clearing IC308 after overcurrentdetection, automatic recovery is not performed and thepower must be turned on again.
