Bias Conditions
∗1Progressive scan mode, 2/8-line readout mode, 2/4-line readout mode, center scan modes (1) and (3),
and AF modes (1) and (2)
∗22-line addition mode and center scan mode (2)
∗3VL setting is the VVL voltage of the vertical clock waveform, or the same voltage as the VL power supply
for the V driver should be used.
∗4Substrate voltage (VSUB2) setting value indication
The substrate voltage (VSUB) for modes without line addition is generated internally.
The substrate voltage setting value for use with vertical 2-line addition is indicated by a code on the
bottom surface of the image sensor. Adjust the substrate voltage to the indicated voltage.
VSUB2 code – 1-digit indication

VSUB2 code
The code and the actual value correspond as follows.
[Example] "h" indicates a VSUB2 setting of 11.6V.
∗5Do not apply a DC bias to the reset gate clock pin, because a DC bias is generated within the CCD.
