Description
The GS2986 is a multi-rate serial digital reclocker designed to automatically recover the embedded clock from a digital video signal and retime the incoming video data. It will recover the embedded clock signal and retime the data from a SMPTE 424M, SMPTE 292M, or SMPTE 259M-C compliant digital video signal. A serial host interface provides the ability to configure and monitor multiple GS2986 devices in a daisy-chain configuration. Adjustable input trace equalization (EQ) for up to 40” of FR4 trace losses, and adjustable output de-emphasis (DE) for up to 20” of FR4 trace losses, can be configured via the host interface. The GS2986 can operate in either aut...
