DESCRIPTION
A vertical transfer pulse for CCD.
Connect to V1AX pin of the vertical driver IC.
For details, see "CONNECTION OF VERTICAL TRANSFER PULSES".
A vertical transfer pulse for CCD.
Connect to V2AX pin of the vertical driver IC.
For details, see "CONNECTION OF VERTICAL TRANSFER PULSES".
A vertical transfer pulse for CCD.
Connect to V3AX pin of the vertical driver IC.
For details, see "CONNECTION OF VERTICAL TRANSFER PULSES".
A vertical transfer pulse for CCD.
Connect to V4AX pin of the vertical driver IC.
For details, see "CONNECTION OF VERTICAL TRANSFER PULSES".
A pulse that sweeps the charge of the photo-diode
for the electronic shutter. Connect to OFD pin of CCD
through the vertical driver IC and DC offset circuit.
Held at H level at normal mode.
Supply of +3 V power.
A grounding pin.
A pulse that transfers the charge of the photo-diode to
the vertical shift register.
For details, see "CONNECTION OF VERTICAL TRANSFER PULSES".
A pulse that transfers the charge of the photo-diode to
the vertical shift register.
For details, see "CONNECTION OF VERTICAL TRANSFER PULSES".
The pulse is used in color separator. The signal
switches H and L at every line.
H : R color line
L : B color line
Write enable output for low-speed shutter pulse.
A test pin. Set open or to L level in the normal mode.
A pulse that corresponds to the cease period of the
horizontal transfer pulse.
A pulse to clamp the optical black signal.
Output stays low during the absence of effective pixels
within the vertical blanking.
A pulse to clamp the signal. The phase is same as BCPX
(pin 14). This pulse is continuous at horizontal cycle.
A pulse to clamp the dummy outputs of CCD. The pulse
stays high during the sweep-out period.
A grounding pin.
