AMIS-710225: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710225 (PI225MC-A6) is a contact imaging sensor (CIS) module, which is composed of 13 AMIS-720220 (PI3020) sensor
chips. The AMIS-720220 is a 200 dots per inch (dpi) 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-710225 is
suitable for scanning A6 size (104mm) documents with 8 dots per millimeter (dpm) resolution. Applications include ticket, check and
card scanners, variety of mark readers, and other automation equipment.

3.0 Functional Description
The AMIS-710225 imaging array consists of 13 sensors that are cascaded to provide 832 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-710225 module.
Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing which
has a cover glass which 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-710225 is shown in Figure 1 and the block diagram in Figure 2.

Tint: Line scanning rate or integration time int is determined by the interval of two start pulses (SP). The module was test at 180us, but it will operate to 167us with
clocking speed of 5.0MHz.
f: main clock frequency he module was tested at 5.0MHz, but electrically it reliably operates above 5.0MHz, but with a minimum integration time of 167µsec.
Vpavg = ∑ Vp(n)/832
Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%
Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the non-uniformity percentage pixel to pixel
Ud = Vdmax – Vdmin
Vdmin is the minimum output on a black document (O.D.=0.8)
Vdmax: maximum output voltage of black document (O.D.= 0.8)
MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]. DOF range is defined with the MTF
MTF is measured at glass surface and at 0.4mm from the glass > 50 percent and peaks at approximately mid-point of 0.2mm.
Vmax: maximum output voltage at 50 lp/inch (At 1/2 of the optical Nyquest Frequency)
Vmin: minimum output voltage at 50lp/inch
O.D. = optical density
lp / inch: line pair per inch
