tf(CLK)

Allow CLK pulse transition from “high” to “low” only one time while ST pulse is “high”.

Integration time is determined by the interval between start pulses.

Only the switching noise component is output from the Dummy Video line.

Do not use the Dummy Video output during integration readout.

The INT signal is not needed between EOS and the rising edge of the next ST signal.
