Description
Analog ground
Power supply
Analog ground
No connection
Analog ground
Analog video signal output; positive polarity
Analog ground
Analog ground
Digital ground
Digital output signal indicating end of scan; negative logic
Digital ground
Digital output signal for A/D conversion; positive logic
Digital ground
Digital input signal for operating the circuit at the rising edge (in case of
C7885G, output signal)
Digital ground
Digital input signal for initializing the circuit; positive logic. (in case of
C7885G, output signal)
Interval of these pulses equals the integration time of the sensor.
