Semtech GS12090 – Configurable 12G UHD-SDI Reclocking Adaptive Cable Equalizer/Cable Driver

The GS12090 is a low-power, configurable multi-rate re-timing cable equalizer/cable driver supporting rates up to 12G UHD-SDI. It can be configured to equalize or drive signals over 75 Ohm coaxial cable. It includes DC restoration to compensate for the DC content of SMPTE pathological test patterns. Since the GS12090 is a re-timing device, extremely low output jitter is achievable even at extended cable/trace lengths.
