AMIS-710214 Datasheet | AMI SEMICONDUCTOR

Description The AMIS-710214 (PI214MC-DR) is a contact image sensor (CIS) module with an additional on-board circuit that digitizes the analog pixels from the CIS image sensor to a “background-tracking”, two-level digital output signal. It is based on AMI Semiconductor’s CIS module that employs MOS image sensor technology to gain its high-speed performance and high sensitivity. The AMIS-710214 is suitable for scanning documents with width of 216mm and with resolution of 8 dots per millimeter (dpm). It has broad applications, but is specially designed for the following areas: - Where data pression is required, such as in data transmissions. - Where ponent pin-out count must be kept to a minimum. The background-tracking-digitizing circuits in the AMIS-710214 have been referred to as the “dynamic threshold” two-level A/D converter. For the purpose of describing the module’s characteristics this “dynamic threshold” processing circuit shall herein be referred to as the “tracking digitizer”. 2.0 Key Features - - - - - - - - - Light source, lens and sensor are integrated into a single module 8dpm resolution, 216mm scanning length Up to 440µsec/line scanning speed, with 4.0MHz pixel rate (See Table 3, Note 2) Wide dynamic range Two-level tracking digital output (“Dynamic Threshold Digitizer”) Red (660nm) light source (other colors are available) pact size ≅ 19.5mm x 21.5mm x 232mm Low power Light weight 3.0 Module Description ..

AMIS-710214: 200dpi Two Level Digital Output Module Data Sheet The AMIS-710214 module consists of 27 sensors that are cascaded to provide 1728 photo-detectors with their associated multiplex switches and a digital shift register that controls its sequential readout. Mounted in the module is a one-to-one graded-indexed micro lens array that focuses the scanned documents to image onto its sensing plane. A buffer amplifier amplifies the video pixels from...
