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.

Table 4. Electro-Optical Characteristics at 25 C Notes: 1. Tint: Tint is the line scanning rate or integration time. Tint is determined by the interval of two SP's; start pulses. 2. fclk: fclk is the main clock frequency. 3. Vpavg: Vpavg = a Vp(n)/2496; where n=1, 2, 3...., 2496. 4. Up: Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100%. where Vpmax = the maximum V(n) and Vpmin = the minimum V(n) 5. Upad: Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%. Upadj is the non-uniformity in percent between adjacent pixels, Where Vp(n) is the nth pixel in the line scan. 6. Ud: Ud = Vdmax - Vdmin. Vd = the average dark output level. Vdmin is the minimum output voltage on a black document (LED is turned off). Vdmax is the maximum output voltage on a black document (LED is turned off). 7. MTF: MTF = [(Vpmax - Vpmin) / (Vpmax + Vpmin)] x 100 [%]; tested on a 300 lp/inch target. Vmax: maximum output voltage at 50 lp/in and Vmin: minimum output voltage at 50 lp/in, where lp/in is the line pairs per inch.

Table 5. Recommended Operating Conditions at 25 C Note: 1. Electrically, including the image sensors, the circuits will operate above 5.5 MHz with Tint at 455 s. However the light power is fixed, hence with the shorter integration time, the exposure is reduced. This reduction limits the specification call out to integration time of 500 s at 5.0MHz for 1.0 V output.
