AMIS-710627-A4, AMIS-710628-A4, AMIS-710629-A4: 600dpi CIS Modules Data Sheet 1.0 General Description The AMIS-710627-A4 (PI627MC-A4), AMIS-710628-A4 (PI628MC-A4) and AMIS-710629-A4 (PI629MC-A4) are a family of contact image sensor (CIS) modules, using MOS image sensor technology for high-speed performance and high sensitivity. They contain a plete optical imaging system that includes the light source and focusing elements. The modules’ contact image sensor is divided into four sections, each with its own video output and identical processing circuits allowing for high scanning speeds. Each module es with its own particular LED light source, which have different maximum light power outputs. Since the light power limits the exposure, which is proportional to the product of scanning speed and light power, each module will have a different maximum scanning speed and signal output voltage. The modules can be used for scanning A4 size (216mm) documents with 23.62 dots per millimeter (dpm) resolution. Applications include document scanning, mark readers, gaming, and office automation equipment. 2.0 Key Features - - - - - - - - - LED light source, lens and sensor are integrated into a single module Ultra high-speed Four parallel analog video outputs, clocked as high as 5.5MHz 270µsec/line scanning speed @ 5.0MHz clock rate for the red light source 23.62dots/mm resolution, 216mm scanning length Wide dynamic range Standard A4 size ≅ 14.5mm x 19.5mm x 232mm Low power Light weight 3.0 Functional Description .. Each of the three modules consists of 27 AMIS-720639 (PI3039) image sensors cascaded together. Each sensor consists of 192 photo-sensing elements (pixels), resulting in a module 5184 pixels long. These image sensors have associated multiplex switches that are sequentially accessed with its digital shift register. In addition, each has a chip-select switch that functions to activate its preceding sensor on the cascaded sequence, after its...
