Note

(1)

Applies to both CP and SP.

(2)

The output is a current that is proportional to the charges, which are

integrated on the phototransistor’s base via photon-to-electron conversion.

For its conversion to voltage pixels see Figure 4, Video Pixel Output Structure

in section Output Circuit Of The Image Sensor.

(3)

Although the clock frequency, Fclk, will operate the device at less than

100KHz, it is recommended that the device be operated above 500KHz to

avoid complication of leakage current build-up. In applications using long CIS

module length, such as an array of image sensor > 27, increases the readout

time, i.e., increases Tint, hence, leakage current build-up occurs.

(4)

The clock duty cycle typically is normally set to 25 %. However, it can operate

with duty cycle as large as 50 %, which will allow more reset time at the

expense of video pixel readout time. At clock frequencies approaching 5.0

MHz it is recommended to use 50% duty cycle to allow more time for the

signal pixel to integrate and settle.
