12G UHD-SDI Retiming Cable Driver

Add to Watch List

The GS12181 is a low-power, multi-rate, serial digital retiming cable driver supporting 12G UHD-SDI. It is designed to receive 100ohm differential input signals, automatically recover the embedded clock from the digital video signal and re-time the incoming data, and transmit the re-timed signal over 75ohm coaxial cables.
