AMIS-710414-A4: 400dpi CIS Module  
Data Sheet  
Four Parallel Video Outputs for RED + IR Light Source  
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  
respective outputs, 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.
