AMIS-710227, AMIS-710228, AMIS-710229: 200dpi CIS Module Data Sheet  
1.0 General Description  
The AMIS-710227 (PI227MC-A4), AMIS-710228 (PI228MC-A4) and AMIS-710229 (PI229MC-A4) are a family of contact image sensor  
(CIS) modules. As a family group they are called AMIS-710227/228/229 modules. They are long-contact image sensor modules using  
MOS image sensor technology for high-speed performance and high sensitivity. They contain their own complete optical system  
including the light source; accordingly, they make a very compact imaging system. The four parallel video outputs give this family of CIS  
modules their high-speed performance. They all possess identical electrical circuit components, as well as the mechanical and optical  
components, except for their LED light sources. Accordingly, they differ in their specification because the different light sources limits  
the effective high-speed performance. The three modules are suitable for scanning A4 size (216mm) documents with 8 dots per  
millimeter (dpm) resolution. Applications include document scanning, mark readers, gaming and office automation equipment.  
2.0 Key Features  
Light source, lens and sensor are integrated into a single module

Four parallel analog video outputs clocked at 5.0MHz  
90µsec/line scanning speed @ 5.0MHz clock rate with optional light sources, selected from the option of three above modules  
8dpm resolution, 216mm scanning length  
Wide dynamic range  
LED light source (selectable among the three above modules)  
Standard A4 size 14mm x 19mm x 232mm  
Low power  
Light weight  
3.0 Functional Description  
Each of the three modules in the family, AMIS-710227/228/229, consists of four major components. The first of them is the printed  
circuit board (PCB) on which the 27 imaging chips, AMIS-720220 (PI3020), are bonded. These sensor chips, produced by AMI  
Semiconductor, are monolithic devices with 64 photo-sensing elements. Each of 27 chips are complete self-contained scanning chips  
and have their control circuits integrated in the chips, so that they can be cascaded to provide 1728 photo-element modules. The AMIS-  
720220 chips are integrated with the photo sensors' associated multiplex switches, a digital shift register and chip selection switch. The  
chip's shift register sequentially clocks out the integrated image charges from each sensing element and passes them through the chip-  
select switch and out onto the video line. The chip-select switches are sequentially switched as each of the predecessor chips  
completes its scan. These 27 sensors, bonded on a PCB, are grouped into four sub-cascaded sections. Each contiguously cascaded  
chips section is connected on separate video lines, resulting in four video outputs VOUT1, VOUT2, VOUT3, and VOUT4. Before the  
signal, charges from the four video lines appear at their respective outputs where they are converted to signal voltages by four on-board  
buffer amplifiers, one for each of its corresponding video section. The first three sections VOUT1, VOUT2 and VOUT3 have seven  
sensor chips, while the VOUT4 has six sensor chips. Since each sensor chip has 64 pixels, there are a total of 1728 pixels. See Figure
