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.

2.0 Key Features

• 600 and 300dpi selectable resolutions

• 23.6dpm and 11.8dpm, 216mm scanning length

• 344 or 172 image sensor elements (pixels)

• Low power-single power supply at 3.3V

• Light source, lens and sensor are integrated into a single module

• High speed page scan - up to 1.30msec/line @ 4MHz pixel rate

• Analog output

• RGB color LED light source

• Compact size ≅ 12.3mm x 18.9mm x 23mm

• Light weight

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.

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.
