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 (high frame rate readout, etc.) that do not use the mechanical shitter,
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 10ms 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 two fields or more 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.
