™ Peripheral Imaging Corporation PI207MC-A4 200DPI CIS Module Engineering Data Sheet Key Features • Light source, lens, and sensor are integrated into a single module • 8 dpm resolution, 216 mm scanning length • Dual LED light source, IR and Red, with a line scan time to 347 msec @ 5 MHz • Wide dynamic range • Analog output • Compact size @ 14.5 mm x 19.5 mm x 232 mm • Low power • Light weight General Description The PI207MC-A4 is a CIS module containing contact image sensors, using MOS image sensor technology for high-speed performance and high sensitivity. The PI207MC-A4 is suitable for scanning A4 size (216 mm) documents with 8 dots per millimeter resolution. Applications include fax machines, game systems, variety of mark readers, and other automation equipment requiring document scanners. Functional Description The PI207MC-A4 imaging array consists of 27 PI3033B sensors, produced by Peripheral Imaging Corp, 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 onboard amplifier processes the video signal to produce a sequential stream of video at the output pin of the PI207MC-A4 module. Illumination is 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 pin 1 location, see Figure 4, Overall View of the Module Housing. PAGE 1 OF 7 - PI207MC-A4, 11/11/03 A cross section of the PI207MC-A4 Module is shown in Figure 1 and a block diagram in Figure 2.

Electro-Optical Characteristics at 25° C Notes. 1. Tint is the line scanning rate or integration time. Tint is determined by the interval of two start pulses, SP. The integration time of 347msec is set at the factory. For additional comments, see note (1) under Table 5, Recommended Operating Conditions. 2. fclk: main clock frequency. 3. Vpavg = å Vp(n)/1728. 4. 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. 5. 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. 6. Ud = Vdmax – Vdmin. Vd = the average dark output level. Vdmin is the minimum output voltage on a black document (LED is turned off). Vdmax is the maximum output voltage on a black document (LED is turned off). 7. MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%] Vmax: maximum output voltage at 50 lp/in and Vmin: minimum output voltage at 50 lp/in, where lp/in is the line pairs per inch.

Recommended Operating Conditions at 25°C Note. 1. Electrically, including the image sensors, the circuits will operate above 5.5 MHz with Tint at 316 µs. 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 0.347 ms at 5.0MHz for 1.0 V output.
