AMIS-710651-A4: Color CIS Module
Data Sheet
1.0 Description
The AMIS-710651-A4 (PI651MC-A4C) is a color contact image sensor (CIS) module. The module contains 15 image-sensor chips,
AMIS-720058 (PI6058E), a product of AMI Semiconductor. These chips are sequentially cascaded to provide a line array of photo-
detectors. Each photo-detector in the image sensor possesses its own independent processing circuit. As the photo-sensors’ digital
shift register scans the image sensor chip, it sequentially produces the video signals at the output of the image array. The AMIS-
710651-A4’s mechanical outline drawing is shown in Figure 6.

3.0 Overview
The AMIS-710651-A4 has a 216mm read width. Its minimum line rate is 1.30ms/line with a maximum clock pulse (CP) equal to 4.0MHz
(pixel rate (PRATE) of 4.0MHz). Unless stated otherwise, all data was taken with CP = 3.0MHz (PRATE = 3.0MHz) and an integration
time of 1.75ms/line. The sensor photo-site density is 23.64elements/mm. The module has one analog video output, two clock inputs,
clock and start pulse (CP and SP), one reference voltage input for the amplifier output bias level control, one power supply input and
four LED inputs.

Pixel rate
Note:
Since the light power is fixed, if the line-scan rate is set proportional to the clock rate, then the integration time reduces as the clock frequency is increased, hence its
exposure. The reduction in the exposure proportionately reduces the video output. Accordingly, the signal-to-noise ratio reduces as the frequency increased.
