General Description
The PI625MC-A6 is a contact-imaging sensor, CIS, module, which is composed of 13 PI3039 sensor chips.
The PI3039 is a 600 DPI solid-state line imaging array, also a product of Peripheral Imaging Corporation.
This imaging device is fabricated using MOS imaging sensor technology for high-speed performance and
high sensitivity. The PI625MC-A6 is suitable for scanning A6 size (104 mm) documents with 23.62 dots per
millimeter resolution. Applications include ticket, check and card scanners, variety of mark readers, and
other automation equipment.
Functional Description
The PI625MC-A6 imaging array consists of 13 sensors that are cascaded to provide 2496 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. The on-board amplifier processes the video signal to produce a sequential
stream of video at the video output pin of the PI625MC-A6 module.
Illumination is by means of an integrated LED light source. All components are housed in a small plastic
housing which has a cover glass that acts as the focal point for the object being scanned and protects the
imaging array, micro lens assembly, and LED light source from dust. I/O to the module is the 10-pin
connector located on one end of the module.
