AMIS-710200 Datasheet | AMI SEMICONDUCTOR

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 437µsec/line scanning speed @ 4.0MHz clock rate Wide dynamic range Analog output 660 Red LED light source pact 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 plete 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 pletes its scanning process. AMI Semiconductor - May 06, M-8-001 .amis.
