1.0 General Description
The AMIS-710224-A6 (PI224-MC-A6) is a contact imaging sensor (CIS) module composed of 13 AMIS-720033 (PI3020) image sensor
chips. The AMIS-720033 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-710224-A6 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-710224-A6 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-710224-A6 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-710224-A6 is shown in Figure 1 and the block diagram in Figure 2.

Tint: line scanning rate or integration time; tint is determined by the interval of two SP. The module was tested at 180us, but it will operate to 167us with a clocking
speed of 5.0MHz.
f: main clock frequency The 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 measure at glass surface and at 0.4mm from the glass > 50 % 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
