The following diagrams show 4-bit multiplexed output data and MCLK, VSMP and input video
requirements for operation of the most commonly used modes as shown in Table 3. The diagrams are
identical for both CDS and non-CDS operation.
Note that for extended Mode 4 operation (MCLK:VSMP ratios of 2n:1 where n  4) the latency is
given by:
Latency (in MCLK periods) = 16.5 + ( n – 4 ) * 2
