O3MR1
OFD pulse output
A pulse that sweeps the charge of the photo-diode for
the electronic shutter. Connect to OFD pin of the CCD
through the vertical driver IC and DC offset circuit.
Held at H level in normal mode.
A vertical transfer pulse for the CCD.
Connect to V
1X
pin of vertical driver IC.
A pulse that transfers the charge of the photo-diode to
the vertical shift register.
Connect to VH
1AX
pin of vertical driver IC.
A pulse that transfers the charge of the photo-diode to
the vertical shift register.
Connect to VH
1BX
pin of vertical driver IC.
A vertical transfer pulse for the CCD.
Connect to V
2X
pin of vertical driver IC.
A vertical transfer pulse for the CCD.
Connect to V
3X
pin of vertical driver IC.
A pulse that transfers the charge of the photo-diode to
the vertical shift register.
Connect to VH
3AX
pin of vertical driver IC.
A pulse that transfers the charge of the photo-diode to
the vertical shift register.
Connect to VH
3BX
pin of vertical driver IC.
A vertical transfer pulse for the CCD.
Connect to V
4X
pin of vertical driver IC.
A grounding pin.
Supply of +3.3 V power.
Supply of +3.3 V power.
A pulse for pre-blanking. This pulse is controlled by
serial data BLKCNT.
BLKCNT = H; This pulse stays low during the
absence of effective pixels within the
vertical blanking or during the
sweepout signal.
BLKCNT = L; Continuous pulse
The output phase of PBLK is selected by serial data.
