Set to A in the table below in most cases.
To sequentially read out signals from two or more sensors linearly connected, set the 1st sensor to A and the 2nd or later
sensors to B. The CLK and RESET pulses should be shared with each sensor and the video output terminal of each sensor
connected together.
A Parallel readout, serial readout at 1st sensor
B Serial readout at 2nd and later sensors

I Readout circuit
Check that pulse signals meet the required pulse conditions before supplying them to the input terminals.
Video output should be amplified by an operational amplifier that is connected close to the sensor.
