8/10/12-bit YCbCr422 with Embedded Syncs
This format is another variation of the YCbCr formats. The bus width is further reduced by half
compared from the previous YCbCr 4:2:2 formats, to either 8-bit, 10-bit or 12-bit. To compensate for
the halving of data bus, PCLK is doubled. With the double-rate input clock, luminance channel (Y) and
chroma channels (Cb or Cr) are alternated.
