Note) Substrate bias control
1. Connect the ground resistor (VR1) shown below to the CSUB pin by each readout mode
in order to secure the saturation signal described on the image sensor characteristics.
ɾProgressive scan readout mode
: 2.0kΩ
ɹç ç ɾHigh frame rate readout mode
: 3.8kΩ
ɹç ç ɾHigh frame rate 2 pixels addition mode: Ground resistor should not be connected.
ç 2. If the substrate bias control signal is set to high level, and the ground resistor (VR1) connected
to CSUB pin is not grounded at 55ms before the exposure time starts because tf is late, the internal
generation voltage (VSUB) may not fall enough.Substrate bias adjustment control signal VSUB Cont.
