18.104.22.168. SD-SDI Timing Jitter With External VCXO Which Receive FVH Sync Signals
In Intel Agilex Intel® Agilex™ device family, this signal is not accurate enough to clock the external VCXO in SD-SDI mode for genlocking purpose. As a workaround, Intel recommends to use an external sync separator to generate this signal to the external VCXO. Alternatively, you can use parallel loopback without VCXO design example.
