Note) Consider the frequency at free run (no signal). When the above characteristic specification is not
satisfied at free run, operating guarantee is not performed as serial transfer.

Note) During external clock input, set serial data HR to L. The pulse synchronized with the horizontal sync
signal is generated by detecting the front edge of horizontal sync signal and then resetting internal PLL
counter.
