Window pulse output 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 VDD with R (≥ 47 k$).
40 FR
O4MA3
A pulse to reset the charge of output circuit.
Reset pulse output
Connect to ØR pin of CCD through the DC offset circuit.

– Power supply
Supply of +5 V power.
42 FH2
O4MA3
Horizontal transfer
pulse output 2
A pulse to drive horizontal CCD shift register.
Connect to ØH2 pin of CCD.
43 GND
–
– Ground
A grounding pin.
44 FH1
O4MA3
Horizontal transfer
pulse output 1
A pulse to drive horizontal CCD shift register.
Connect to ØH1 pin of CCD.
