1.0 General Description
The AMIS-710625-A6 (PI625MC-A6) is a contact imaging sensor (CIS) module, which is composed of 13 AMIS-720639 (PI3039)
sensor chips. The AMIS-720639 is a 600dpi solid-state line imaging array, also a product of AMI Semiconductor. This imaging device
is fabricated using MOS imaging sensor technology for high-speed performance and high sensitivity. The AMIS-710625-A6 is suitable

3.0 Functional Description
The AMIS-710625-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 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 AMIS-710625-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.
The cross section of the AMIS-710625-A6 is shown in Figure 1 and its block diagram in Figure 2.

Tint: Line scanning rate or integration time; tint is determined by the interval of two SP.
fclk: main clock frequency.
Vpavg = ∑ Vp(n)/2496; where n=1, 2, 3...., 2496.
Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100%, where Vpmax = the maximum V(n) and Vpmin = the minimum V(n).
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.
Ud = Vdmax – Vdmin.
Vd = the average dark output level.
Vdmin is the minimum output on a black document (LED is turned off).
Vdmax: maximum output voltage of black document (LED is turned off.)
MTF = [(Vpmax - Vpmin) / (Vpmax + Vpmin)] x 100 [%]; tested on a 300 lp/inch target.
Vmax: maximum output voltage at 50lp/in and Vmin: minimum output voltage at 50lp/in, where lp/in is the line pairs per inch.

Note:
1.
Electrically, including the image sensors, the circuits will operate above 5.5MHz with tint at 455µs. 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 500µs at 5.0MHz for 1.0V output.
