AMIS-710401-A4 Datasheet | AMI SEMICONDUCTOR

Description The AMIS-710401-A4 (PI401MC-A4) is a contact image sensor (CIS) module using MOS image sensor technology for high-speed performance and high sensitivity. These CIS modules contain a plete optical imaging system that includes the light source and focusing elements. The MOS image sensors are mounted on a printed circuit board (PCB) and housed in an A4 size module. They contain video processing circuits, allowing for high scanning speeds. The module es with its LED light source, which provides the light power. Since the light power limits the exposure, which is proportional to the product of scanning speed and light power, the module’s maximum scanning speed and signal output voltage are limited, in this case with the Red light source, to a 5.5MHz clock rate. The module is designed for scanning A4 size (216mm) documents with 16 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 660nm LED light source Analog video, pixel rate as high as 5.5MHz 630µsec/line minimum scanning speed @ maximum of 5.5MHz clock rate 16 dots/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 modules consists of 27 AMIS-720442 (PI3042) image sensors, serially cascaded together. Each sensor consists of 128 photo-sensing elements (pixels), resulting in a module with a length of 3456 pixels. These image sensors, which are cascaded in a sequence to form a single line array, contain associated multiplex switches, which are sequentially accessed with its digital shift register. Each register has a chip-select switch, which activates its shift register upon the pletion of its preceding sensor’s scan. In turn, after pleting its own scan the register activates its successor’s register. The start...
