AMIS-710200:200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710200 (PI200MC-A4) is a contact image sensor (CIS) module. It is a long CIS using MOS image sensor technology for high-speed performance and high sensitivity. The AMIS-710200 is suitable for scanning A4 size (216mm) documents with 8 dots per millimeter (dpm) resolution. Applications include document scanners, mark readers and other office automation equipment.
2.0 Key Features
* * * * * * * * * Light source, lens and sensor are integrated into a single module 8dpm resolution, 216mm scanning length 437sec/line scanning speed @ 4.0MHz clock rate Wide dynamic range Analog output 660 Red LED light source Compact size - 20.5mm x 21.5mm x 232mm Low power Light weight
3.0 Functional Description
The AMIS-710200 imaging array consists of 27 sensors, AMIS-720220 (PI3020), produced by AMIS. The sensor is a monolithic chip with an array of 64 photo sensing elements, of which 27 are cascaded to provide 1728 photo-detectors. These cascaded chips are contiguously aligned in a single row and bonded to the printed circuit board (PCB). See Figure 1, AMIS-710200's block diagram. This st configuration allows a stream of sequential video pixels to be read from its output port, for example, starting from the first pixel, 1 , th located next to the connector end of the module and continues to and through the last pixel, 1728 . Each chip contains a complete control circuitry. Integrated within monolithic chip is 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.

Figure 1: AMIS-710200 Block Diagram
Figure 2 shows a mechanical cross section of the module's internal structure. Mounted in the module is a number of components. These components function together to provide the module a complete integrated system. The LED light bar illuminates the documents through the window and reflection from the imaged documents is picked up and focused by the one-to-one graded indexed micro lens array. The lens, through the glass window, focuses the scanned images from the document onto the sensing plane of the sensor chips, which is mounted on the PCB. During the imaging process, the document is passed across the glass window's surface. The PCB not only has the sensor chips mounted on it, but it has an on-board amplifier, a clock buffer for both the start pulse (SP), and the module's master clock (CP) buffer. This amplifier processes the pixel charges from the image sensor chips and converts them into voltage signal to produce a sequential stream of video at the output pin of the AMIS-710200 module. All these discussed components are housed in a small plastic housing which has a cover glass, the window. This housing with its sealed windows protects the imaging array, the micro lens assembly and the LED light source from dust.

4.0 Pin Out Description
There is one connector located at the end of the module. The outline of the module in Figure 4 of the mechanical section illustrates the connector location. With the module window facing down on flat surface, the viewer looking down on backside of the module and with the connector's pins facing the viewer, the connector is located on the left hand end of the module. The connector is a 2.0mm dual 8pin row with a total of 16 pin connector, part # Berg 88054-X16. Its I/O designation is provided in Table 1. Pin number 1's location is indicated on the module outline. All of the odd pins are on the bottom row with Pin 1 on the edge closest to the end of the module. All of the even pins are on the top row with Pin 2 located adjacent to Pin 1.

Definitions: 1. Tint is the line scanning rate or integration time. Tint is determined by the interval between two start pulses (SP). 2. Fclk is the main clock, CP, frequency. 3. Vpavg = Vp(n)/1728. 4. Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%. 5. Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%. Upadj is the non-uniformity percentage pixel-to-pixel. 6. Ud = Vdmax -Vdmin Vdmin is the minimum dark output voltage, Vd, with light source off. Vdmax: maximum dark output voltage, Vd, with light source off. Vd is measured between the reset level of the video and the dark video signal level. This fixed offset occurs because of the video line is reset to ground after each pixel and before the following pixel. However, because the video signal is amplified and the offset is adjusted to force the average dark video signal near ground, the average dark video signal is only few millivolts from ground and reset level will be below ground. 7. MTF = [(Vpmax - Vpmin) / (Vpmax + Vpmin)] x 100 [%] is the effective algorithm which is used to make the measurements. V(p)max: maximum output voltage at 4.0lp/mm V(p)min: minimum output voltage at 4.0lp/mm. 8. lp / mm: line pair per mm.
