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 on- board 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. PI207MC-A4 Engineering Data Sheet 200DPI CIS Module PAGE 1 OF 7 - PI207MC-A4, 11/11/03 Peripheral Imaging Corporation

Table 1. Pinout Configuration Table 2. Maximum Rating Note. These are the maximum ratings and are not to be used in a prolonged condition. Table 3. Operating Environment
Table 4. Electro-Optical Characteristics at 25° C
- Tint is the line scanning rate or integration time. Tint is determined by the interval of two start
(1) under Table 5, Recommended Operating Conditions.
- fclk: main clock frequency.
- Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100%,
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). where lp/in is the line pairs per inch.
The tabled values are measured at 25º C. Table 5. Recommended Operating Conditions at 25°C
- 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.
- The listed values are measured at ~25º C.
