AMIS-710226: 200dpi CIS Module Data Sheet 1.0 General Description The AMIS-710226 (PI226M-A4) is a contact image sensor (CIS) module using MOS image sensor technology for high-speed performance and high sensitivity. The AMIS-710226 is suitable for scanning A4 size (216mm) documents with 8 dots per millimeter (dpm) resolution. Applications include fax machines, game systems, 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 8dpm resolution, 216mm scanning length 347µsec/line scanning speed possible with optional light sources Yellow-Green LED light source, limits the typical line scan to 695µsec @ 2.5MHz Wide dynamic range Analog output Compact size ≅ 14mm x 19mm x 23mm Low power Light weight 3.0 Functional Description The AMIS-710226 imaging array consists of 27 AMIS-720033 (PI3020) image sensors produced by AMIS, that are cascaded to provide 1728 photo-detectors with their associated multiplex switches and a digital shift register that controls its sequential readout. Mounted in the module is one-to-one graded indexed micro lens array that 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 AMIS710226 module. Illumination is accomplished by means of an integrated Yellow-Green LED light source. 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, protects the imaging array, micro lens assembly, and LED light source from dust. I/O to the module is the 10-pin connector located on one end of the module. For pin 1 location, see Figure 4. The cross section of the AMIS-710226 is shown in Figure 1 and the block diagram in Figure 2.

Tint: line scanning rate or integration time; tint is determined by the interval of two start pulses (SP). This integration time of 695µsec typically set at the factory for Yyellow-Green LED. The minimum integration time of 347us is available at 5.0MHz pixel rate, but it will require optional light sources. fclk: main clock frequency Vpavg = ∑ Vp(n)/1728 Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100% Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100% Upadj is the non-uniformity in percent between adjacent pixels. Ud = Vdmax – Vdmin Vd = the average dark output level. Vdmin is the minimum output on a black document (LED is turned off). Vdmax: maximum output voltage of black document (LED is turned off).
