I/O
Description
O Sensor scan start signal. Pulse width at High level nearly equals sensor integration time.
O Sensor scan sync signal. Sensor starts scanning in synchronization with this signal.
I For A/D conversion timing signals. Positive logic
O
High level at first stage during parallel or serial readout. At second and subsequent stages during
serial readout, this outputs the EOS pulse of preceding stage.
O
High level at first stage during parallel or serial readout. At second and subsequent stages, this
sets to Low level.
O Sensor supply voltage
- Sensor GND
I EOS (end of scan) signal of sensor. Negative logic
I Video output signal. Positive polarity
O Reference voltage
O Sensor gain switching H: high gain, L: low gain
O Photodiode voltage
CN2 [Connector type: DF13-10P-1.25H (50) (made by Hirose Electric)]
Used to connect the first stage to an external I/O during parallel readout or serial readout
For the second and subsequent stages during serial readout, CN2 is used to connect to CN3 at preceding stage.
Pin no.

I/O
Description
I Sensor scan start signal. Pulse width at High level nearly equals sensor integration time.
I Sensor scan sync signal. Sensor and circuit start operating in synchronization with this signal.
O For A/D conversion timing signals. Positive logic
O EOS (end of scan) signal of all sensors during parallel or serial readout. Negative logic
I
NC (no connection) at first stage during parallel or serial readout. At second and subsequent
stages during serial readout, this receives the EOS pulse of preceding stage.
I External setting for sensor gain H: high gain, L: low gain

I +5 V power supply
O Video output signal. Positive polarity
O Video GND
CN3 [CN3 is installed only for C9118-01. Connector type: DF13-12P-1.25H (50) (made by Hirose Electric)]
