12G UHD-SDI Retiming Adaptive Cable Equalizer

Add to Watch List

The GS12141 is a low-power, multi-rate, serial digital retiming cable equalizer supporting 12G UHD-SDI. It is designed to equalize and restore signals received over 75ohm coaxial cable, automatically recover the embedded clock from the digital video signal and re-time the incoming data.
