WIND1 : When connected to EEST (pin 38), the
operation of electronic exposure can be
stopped at the upper side of monitor.
WIND2 : A pulse that picks out the center of CCD output.
At this time, set H level or open at EEST (pin
38). As the output circuit of WIND is N-ch open
drain, connect to V
DD
with R (≥ 47 k$).
A pulse to reset the charge of output circuit.
Connect to
R
pin of CCD through the DC offset circuit.
Supply of +5 V power.
A pulse to drive horizontal CCD shift register.
Connect to
H2
pin of CCD.
A grounding pin.
A pulse to drive horizontal CCD shift register.
Connect to
H1
pin of CCD.
Supply of +5 V power.
An input pin for reference clock oscillation.
Connect to OSCO (pin 47) with R.
