AMIS-710414-A4 Datasheet | AMI SEMICONDUCTOR

Description The AMIS-710414-A4 (PI414MC-A4-R) is a contact image sensor (CIS) module, which uses MOS image sensor technology for highspeed 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 pact 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)....
