AMIS-710207-A4: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710207-A4 (PI207MC-A4) contact image sensor (CIS) module uses MOS image sensor technology for high-speed performance and high sensitivity. The AMIS-710207-A4 is suitable for scanning A4 size (216mm) documents with 8 dots per millimeter (dpm) resolution. Applications include fax machines, game systems, a variety of mark readers, and other automation equipment requiring document scanners.
2.0 Key Features
* * * * * * * * Light source, lens and sensor are integrated into a single module 8dpm resolution, 216mm scanning length Dual LED light source, IR and Red, with a line scan time to 347sec @ 5MHz Wide dynamic range Analog output Compact size 14.5mm x 19.5mm x 232mm Low power Light weight
3.0 Functional Description
The AMIS-710207-A4 imaging array consists of 27 AMIS-720233 (PI3033B) sensors, produced by AMIS, that are cascaded to provide 1728 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 on the image of the scanned documents, then transfers it onto the sensors. The on-board amplifier processes the video signal to produce a sequential stream of video at the output pin of the AMIS-710207-A4 module. Illumination is accomplished by means of integrated LED sources; Red (660nm) and IR (880nm). 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. In addition, it protects the imaging array, micro lens assembly and LED light source from dust. Inputs and outputs (I/O) to and from the module are by a 10-pin connector, JAE 1L-Z-10P-S125L3-E, located on one end of the module. For the Pin 1 location, see Figure 4, overall view of the module house. A cross section of the AMIS-710207-A4 module is shown in Figure 1 and a block diagram in Figure 2.

Tint is the line scanning rate or integration time. Tint is determined by the interval of two start pulses, SP. The integration time of 347sec is set at the factory. For additional comments, see Note (1) under Table 5. fclk: main clock frequency. Vpavg = Vp(n)/1728. Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100%, where Vpmax = maximum pixel amplitude in the line scan and Vpmin = minimum pixel amplitude in the line scan. 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 = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]. Vmax: maximum output voltage at 50lp/in and Vmin: minimum output voltage at 50lp/in, where lp / in is the line pairs per inch.

Electrically, including the image sensors, the circuits will operate above 5.5MHz with tint at 316s. However, the light power is fixed, so with the shorter integration time, the exposure is reduced. This reduction limits the specification call out to integration time of 0.347ms at 5.0MHz for 1.0V output.

The timing characteristics for the I/O clocks are shown in Figure 3. See the timing symbol definitions in Table 6. The listed values are measured at ~25oC.
