My design uses AD24000 with an external sync signal from a video camera. Sync signal comes at 30 Hz. My configuration is:
SYNC_SCAL: 0x0443 = floor(32768/30 -1)
I expect to see DR signal being asserted at a fixed phase offset from the SYNC signal. However, in reality, it randomly drifts relative to the SYNC edge. I would appreciate suggestions.
