    LMH0387 3 Gbps HD/SD SDI Configurable I/O Adaptive Cable Equalizer / Cable Driver1 Features 3 Description

    The LMH0387 3 Gbps HD/SD SDI Configurable I/O1 ST 424, ST 292, ST 344, and ST 259 Compliant

    Adaptive Cable Equalizer / Cable Driver provides a(1)single chip interface to a BNC. The device can be

    Supports DVB-ASI at 270 Mbps configured either in the input mode as an equalizer to Data Rates: 125 Mbps to 2.97 Gbps when receive data over coaxial cable or in the output mode

    as a cable driver to transmit data over coaxial cable.Receiving (DC to 2.97 Gbps when Driving Cable)The same I/O pin is used both for the input and the Equalizes up to 120 Meters of Belden 1694A atoutput functions of the device, allowing the system2.97 Gbps, up to 200 Meters of Belden 1694A at designer the flexibility to use a BNC attached to the1.485 Gbps, or up to 400 Meters of Belden 1694A device as either an input or an output.at 270 MbpsThe device operates over a wide range of data rates Integrated Return Loss Network (No Externalfrom 125 Mbps to 2.97 Gbps (DC to 2.97 Gbps whenComponents Required) driving cable) and supports ST 424, ST 292, ST 344,

    Power Saving Modes and ST 259. The return loss network is integratedwithin the device so no external components are Cable Driver Selectable Slew Raterequired to meet the SMPTE return loss specification. Internally Terminated 100- LVDS ReceiverThe LMH0387 offers designers flexibility in systemOutputs With Programmable Common Mode design and quicker time to market.Voltage and SwingIn the input mode, the LMH0387 features include a Programmable Launch Amplitude Optimization forpower-saving sleep mode, programmable outputReceivercommon mode voltage and swing, cable length

    Cable Length Indication indication, launch amplitude optimization, input signal Single 3.3-V Supply Operation detection, and an SPI interface. In the output mode,

    the LMH0387 features include two selectable slew 48-Pin Laminate TLGA Packagerates for ST 424 / 292 and ST 259 compliance, and Industrial Temperature Range: 40C to 85C output driver power-down control.

    The device is available in a 7-mm 7-mm 48-pin2 Applicationslaminate Thin Laminate Grid Array (TLGA) Package.
