AMIS-710409-A4 Datasheet | AMI SEMICONDUCTOR

Description The AMIS-710409-A4 (PI409MC-A4) is a contact image sensor (CIS) module. It is a long CIS module that uses MOS image sensor technology for high-speed performance and high sensitivity. Its four parallel video outputs give the AMIS710409-A6 its high speed performance. The AMIS-710409-A4 is suitable for scanning A4 size (216mm) documents with 15.8 dots per millimeter (dpi) resolution. Applications include document scanning, mark readers, gaming and office automation equipment. 2.0 Key Features - - - - - - - - - - Light source, lens and sensor are integrated into a single module Ultra high speed Four parallel analog video outputs clocked at 5.0MHz 180usec/line scanning speed @ 5.0MHz clock speed 15.8dpm resolution, 216mm scanning length Wide dynamic range Red light source 660nm Standard A4 size ≅ 14mm x 19mm x 232mm Low power Light weight 3.0 Functional Description The AMIS-710409-A4 imaging module consists of 27 AMIS-720442 (PI3042) imaging chips, produced by AMIS. The sensor chips are monolithic devices with 128 photo sensing elements. Twenty seven of these imaging chips are cascaded to provide a 3456 photoelements module. The AMIS-720442 chips are integrated with the associated multiplex switches of the photo sensors, a digital shift register and a chip selection switch. The shift register sequentially clocks out the integrated image charges from each of the sensing elements and passes them through the chip-select switch and out onto the video line. The chip-select switches are sequentially switched as each predecessor chip pletes its scan. These 27 sensors, bonded on a PCB, are grouped into four sub-cascaded .. sections. Each contiguously cascaded chip section is connected on separate video lines, therefore 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...
