Note: The internal circuit starts operating at the rise of CLK pulse immediately after ST pulse sets to low.
The integration time equals the high period of ST pulse plus 6 CLK cycles.
· The output from 1st channel appears 14 clocks plus 100 ns after the falling edge of ST pulse.
· The EOS pulse is output 25 ns after the falling edge of CLK pulse.
· The output after reading the last pixel (512 ch) is indefinite.
