Description
Pulses for operating the MOS shift register. The video data rate is
equal to the clock pulse frequency since the video output signal is
obtained synchronously with the rise of φ2 pulse.
Pulse for starting the MOS shift register operation. The time interval
between start pulses is equal to the signal accumulation time.
Connected to the anode of each photodiode. This should be
grounded.
Used for restricting blooming. This should be grounded.
Used for restricting blooming. This should be biased at a voltage
equal to the video bias voltage.
Video output signal. Connects to photodiode cathodes when the
address is on. A positive voltage should be applied to the video
line in order to use photodiodes with a reverse voltage. When the
amplitude of φ1 and φ2 is 5 V, a video bias voltage of 2 V is
recommended.
This has the same structure as the active video, but is not
connected to photodiodes, so only spike noise is output. This
should be biased at a voltage equal to the active video or left as an
open-circuit when not needed.
Connected to the silicon substrate. This should be grounded.
This should be pulled up at 5 V by using a 10 kΩ resistor. This is a
negative going pulse that appears synchronously with the φ2
timing right after the last photodiode is addressed.
Should be grounded.
