∗

Progressive scan mode, 2/8-line readout mode, 2/4-line readout mode, center scan modes (1) and (3),

and AF modes (1) and (2)

∗

2-line addition mode and center scan mode (2)

∗

V

L

 setting is the V

VL

 voltage of the vertical clock waveform, or the same voltage as the V

L

 power supply

for the V driver should be used.

∗

Substrate voltage (V

SUB2

) setting value indication

The substrate voltage (V

SUB

) 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.

SUB2

 code

The code and the actual value correspond as follows.

[Example] "h" indicates a V

SUB2

 setting of 11.6V.

∗

Do not apply a DC bias to the reset gate clock pin, because a DC bias is generated within the CCD.
