Function
1
CCD. IN
I
CCD signal input. This pin can handle CCD signal reset levels up to
0.5 Vp-p. The data level is sliced at a maximum saturation output of
1.5 V.
2
SH-GND
P
3
SH-D
I
CDS system ground. This line should be kept as short as possible
since the CDS system handles high frequencies.
This pin controls the charge and discharge speeds of the SH1 circuit.
Leave this pin open when a CCD element with 300,000 or fewer
pixels is used. Set this pin to 5 V when a CCD element with over
300,000 pixels is used.
4
VIDEO-VCC1 P
5
MAX. GAIN
I
AGC amplifier system VCC. Apply 5 V to this pin. Use pin 43 as the
corresponding ground. Either decouple (we recommend using a
power supply separate from the other VCCs for this voltage) or use a
DC-DC converter design so that signal component frequencies do
not leak into this VCC.
AGC maximum gain control.
The value of the maximum gain is:
About 15.5 dB when pin 5 is at 0 V,
About 24 dB when pin 5 is open, and
About 31 dB when pin 5 is at 5 V.
6
CLP. C
B
Charge/discharge capacitor used for post-CDS OPB clamping. We
recommend a value of 0.1 µF for this capacitor.
