The GS12181 is a low-power, multi-rate, serial digitalretiming cable driver supporting 12G UHD-SDI. It isdesigned to receive 100ohmdifferential input signals,automatically recover the embedded clock from the digitalvideo signal and re-time the incoming data, and transmitthe re-timed signal over 75ohmcoaxial cables.Multi-standard operation from 1Mb/s to 11.88Gb/sSMPTE ST 2082-1, ST 2081-1, ST 424, ST 292-1 and ST 259 compliant outputSupport for DVB-ASI at 270Mb/s and MADI at 125Mb/sLow power operation: approx. 310mWAutomatic power down on loss of signalDifferential input support DC-coupling from 1.2V to 2.5V CML logicOn-chip 100ohmdifferential input data terminationProgrammable trace equalization to compensate for up to 20" FR4 at 11.88Gb/s1.8V power supply operationManual bypass for low data rates with slow rise/fall times75ohmcable driver outputs Individually selectable output pre-emphasis topre-compensate for FR4 losses after chip output at 11.88Gb/s High levels of pre-emphasis available (up to 8" of FR4) using higher output driver voltage supplyAutomatic/manual output slew rate controlGSPI serial control and monitoring interfaceCable equalizer bypass Manual Bypass function for low data rates Config
