Semtech | GS2965-INE3

The GS2965-INE3 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, available in a QFN-32 package.

The GS2965 can operate in either auto or manual rate selection mode. In Auto mode, the device will automatically detect and lock onto incoming SMPTE SDI data signals at any supported rate. For single rate data systems, the GS2965 can be configured to operate in Manual mode.
