AMIS-710414-A4: 400dpi CIS Module
Four Parallel Video Outputs for RED + IR Light Source
Data Sheet
1.0 General Description
The AMIS-710414-A4 (PI414MC-A4-R) is a contact image sensor (CIS) module, which uses MOS image sensor technology for high-
speed performance and high sensitivity. The AMIS-710414-A4 is suitable for scanning A4 size (216mm) documents with 15.8 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
15.8dpm resolution, 216mm scanning length
Dual LED light source, RED and IR, with a line scan time to 180µsec @ 5MHz
Wide dynamic range
Analog output
Compact size 14.0mm x 19.5mm x 232mm
Low power
Light weight
3.0 Functional Description
The AMIS-710414-A4 imaging array consists of 27 AMIS-720642 (PI3042) sensors, produced by AMI Semiconductor, which are
cascaded to provide 3456 photo-detectors with their associated multiplex switches and a digital shift register, which controls its
sequential readout. Mounted in the module is a one-to-one graded indexed micro lens array, which focuses on the image of the
scanned documents then transfers it onto the sensors. The on-board amplifier processes the video signal to produce a sequential
stream of video at the output pin of the AMIS-710414-A4 module. These 27 sensors bonded on a printed circuit board (PCB) are
grouped into four sub-cascaded sections. Each contiguously cascaded chip section is connected on separate video lines, accordingly
providing four video outputs, VOUT1, VOUT2, VOUT3, and VOUT4. Before the signal charges from the four video lines appear at their
wwrews.DpeatcatSivheeeotu4tUp.ucotsm, they are converted to signal voltages by four on-board buffer amplifiers; one for each of its corresponding video
sections. The first three sections, VOUT1, VOUT2 and VOUT3 have seven sensor chips, while the VOUT4 has six sensor chips. Since
each sensor chip has 128 pixels, there are a total of 3456 pixels (see Figure 1).
Illumination is accomplished by means of integrated LED sources; Red (65nm) and IR (880nm). All components are housed in a small
plastic housing, which has a cover glass that acts as the focal point for the object being scanned. In addition, it protects the imaging
array, micro lens assembly and LED light source from dust. Inputs and outputs (I/O) to and from the module are facilitated by a 12-pin
connector, EBW-PK23-P012L2-3Z, located on one end of the module. For the location of Pin 1, see Figure 4.
The cross section of the AMIS-710414-A4 module is shown in Figure 1 and a block diagram in Figure 2.
