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 347µsec @ 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.

Note:
1.
Electrically, including the image sensors, the circuits will operate above 5.5MHz with tint at 316µs. 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.
9.0 Timing Characteristics
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.
