AMIS-710225: 200dpi CIS Module Data Sheet 1.0 General Description The AMIS-710225 (PI225MC-A6) is a contact imaging sensor (CIS) module, which is posed of 13 AMIS-720220 (PI3020) sensor chips. The AMIS-720220 is a 200 dots per inch (dpi) solid-state line imaging array, also a product of AMI Semiconductor. This imaging device is fabricated using MOS imaging sensor technology for high-speed performance and high sensitivity. The AMIS-710225 is suitable for scanning A6 size (104mm) documents with 8 dots per millimeter (dpm) resolution. Applications include ticket, check and card scanners, variety of mark readers, and other automation equipment. 2.0 Key Features - - - - - - - - - Light source, lens and sensor are integrated into a single module 8dpm resolution, 104mm scanning length High speed page scan - up to 167µsec/line @ 5MHz pixel rate Wide dynamic range Analog output Red LED light source pact size ≅ 14mm x 19mm x 120mm Low power Light weight 3.0 Functional Description The AMIS-710225 imaging array consists of 13 sensors that are cascaded to provide 832 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 the scanned documents to image onto its sensing plane. The on-board amplifier processes the video signal to produce a sequential stream of video at the video output pin of the AMIS-710225 module. .. Illumination is acplished by means of an integrated LED light source. All ponents are housed in a small plastic housing which has a cover glass which acts as the focal point for the object being scanned and 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. The cross section of the AMIS-710225 is shown in Figure 1 and the block diagram in Figure 2. AMI Semiconductor - May 06,...
