Outline of Operation Timing
(1) Overall Operation Timing
Video signals of one horizontal scanning period are
sampled into the sample and hold circuits at the
timing of the internal sampling pulses of each
output circuit, and data corresponding to the
sampled data are output.

(2) Timing of Video Signal Sampling
If the normal sampling operation and cascade
sequence is 1st, the video signal sampling (internal
sampling signal Sn (n =
1, 2, π, 240
)) is started at the
rising edge of first clock after falling edge of start
pulse.
