16/20/24-bit YCbCr422 with Separate Syncs
YCbCr 4:2:2 format does not have one complete pixel for every clock period. Luminace channel (Y) is
given for every pixel, while the two chroma channels are given alternatively on every other clock
period. The DE period should contain an even number of clock periods.
