Notes)
Substrate bias control
1. The saturation signal level decreases when exposure is performed using the mechanical shutter, so control
the substrate bias.
2. A saturation signal level equivalent to that for continuous exposure can be assured by connecting a 2.7kΩ
grounding registor to the CCD CSUB pin.
Drive timing precautions
1. Blooming occurs in modes (2× speed (1), 8× speed, etc.) where exposure is not completed by closing the
mechanical shutter, so do not ground the connected 2.7kΩ resistor.
2. tf is slow, so the internally generated voltage VSUB may not drop to a sufficiently low level if the substrate
bias control signal is not set to high level 30ms before entering the exposure period and the 2.7kΩ resistor
connected to the CSUB pin is not grounded.
3. The blooming signal generated during exposure in mechanical shutter mode is swept by providing one
field or more (two fields is recommended) of idle transfer through vertical register high-speed sweep
transfer from the time the mechanical shutter closes until sensor readout is performed. However, note that
the VL potential and the φSUB pin DC voltage sag at this time.
4. When exposure time is several seconds or more, we recommend the sequence that the substrate bias
control is performed just before the completion of exposure (Mechanical shutter is closed.), not before the
start of exposure.
