AMIS-710324-A4: 300dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710324-A4 (PI324MC-A4) is a contact image sensor (CIS) module. It is a dual-analog-output contact image sensor, using
MOS image sensor technology for high-speed performance and high sensitivity. The AMIS-710324-A4 is suitable for scanning A4 size
(216mm) documents with 11.8 dots per millimeter (dpm) resolution. Applications include fax machines, game systems, a variety of mark
readers and other automation equipment requiring document scanners.
2.0 Key Features
Light source, lens and sensor are integrated into a single module
11.8dpm resolution, 216mm total scanning length (2592 pixels long)
Two independent analog outputs (split into two sections of 1248 pixels and 1344 pixels)
Up to 270µsec/line scanning speed with red light source
Wide dynamic range
Red LED light source
Compact size 14mm x 19mm x 232mm
Low power
Light weight
3.0 Functional Description
The AMIS-710324-A4 imaging array consists of 27 sensors, AMIS-720321 (PI3021), produced by AMI Semiconductor. The sensor is a
monolithic chip with an array of 96 photo sensing elements, of which 27 are cascaded to provide 2592 photo-detectors. Additionally,
these chips give the users the readout flexibility in selecting their desired data format. These cascaded chips are segregated into two
electrically independent sections of 13 chips and 14 chips, but they are still contiguously aligned in a single row, see Figure 1 (the
wwmwo.DduatleaS'shebelot4cUk.cdoimagram). This configuration lends itself to a positional stream of video pixels, whether they are read in parallel or
sequentially from the two output ports.
Each chip contains a set of multiplex switches, and a digital shift register to control the chips sequential readout. Additionally, the chips
contain a chip selection switch that is interrogated in a sequence as each predecessor chip completes its scanning process. Since this
module has two output ports from two independently controlled sections of chips, the users are required to enter a set of control clocks
and power into each section through the two provided connectors located on each end of the module.

Figure 2 depicts a cross sectional pictorial of the module. Mounted in the module is a one-to-one graded indexed micro lens array that
focuses the scanned documents' image onto the chip's sensing line. The sensing line is located along the module's sensor axis, known
as the read line. These photon images are transformed into proportional video charges and processed by two on-board amplifiers. The
video signal from the amplifier transmits a sequential stream of video pixels to the video output pin of the AMIS-710324-A4 module.
Also mounted in the housing is a LED light source. Figure 2 shows the LED bar and its illumination path. The path traces the ray from
the LED and is reflected from the document and focused through the ROD lens and onto the sensors. All these components are housed
in a small plastic housing with a cover glass. The cover glass serves as a window with the outside surface as the focal point for the
image on the document. It also serves to protect the imaging array, the micro lens assembly and the LED light source from dust.
