AMIS-710239-A3: 200dpi CIS Module Data Sheet 1.0 General Description The AMIS-710239-A3 (PI239MC-A3-R) is a contact image sensor (CIS) module. It is a long contact image sensor, which uses MOS image sensor technology for high speed performance. The AMIS-710239-A3 is suitable for scanning A3 size (307mm) documents with eight dots per millimeter (dpm) resolution. Hence, there are 38 AMIS-720233 (PI3033B) image sensors in the module, providing a total of 2432 pixels in a sequence. The sensors are.

AMIS-710239-A3: 200dpi CIS Module Data Sheet 1.0 General Description The AMIS-710239-A3 (PI239MC-A3-R) is a contact image sensor (CIS) module. It is a long contact image sensor, which uses MOS image sensor technology for high speed performance. The AMIS-710239-A3 is suitable for scanning A3 size (307mm) documents with eight dots per millimeter (dpm) resolution. Hence, there are 38 AMIS-720233 (PI3033B) image sensors in the module, providing a total of 2432 pixels in a sequence. The sensors are 200 dots per inch (dpi) solid-state line imaging array, also a product of AMI Semiconductor. Applications include document scanners, mark readers and other office automation equipment. 2.0 Key Features • • • • • • • • • Light source, lens and sensor are integrated into a single module 8dpm resolution, 307mm scanning read length High speed page scan - up to 490µsec/line @ 5MHz pixel rate Wide dynamic range One analog output Super super Red (630nm) LED light source Compact size ≅ 20.5mm x 21.5mm x 324mm Low power Light weight 3.0 Functional Description The AMIS-710239-A3 imaging array consists of 38 sensor chips in the module, which are sequentially cascaded to provide 2432 photodetectors with their associated multiplex switches and a digital shift register, which controls its sequential readout. Mounted in the module is a one-to-one graded indexed micro lens array, which 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. Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing which www.DataSheet4U.com has a cover glass acting 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 AMIS710239-A3 is shown in Figure 1 and the block diagram in Figure 2.

Tint is determined by the interval of two start pulses (SP). The module shall be tested at 490us, but it will operate to us 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. Vpavg = ∑ Vp(n)/2432 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 (6) Ud = Vdmax – Vdmin Vdmin is the minimum output on a black document (O.D. = 0.8) Vdmax: maximum output voltage on a black document (O.D. = 0.8) (7) MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]. The DOF range is defined with the MTF. MTF is a measure at the glass surface and at 0.4mm from the glass > 50 percent and peaks at approximately a mid-point of 0.2mm. Vmax: maximum output voltag.
