AMIS-710404-A8: 400dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710404-A8 (PI404MC-A8) is a contact image sensor (CIS) module. It is a long contact image chip, which uses MOS image sensor technology for high-speed performance and high sensitivity. The AMIS-710404-A8 is suitable for scanning A8 size (57mm) documents with 15.7 dots per millimeter (dpm) resolution. Applications include document scanning, mark readers, gaming and office automation equipment.
2.0 Key Features
* * * * * * * * * Light source, lens and sensor are integrated into a single module 15.7dpm resolution, 57mm scanning length 1.8msec/line scanning speed @ 500kHz clock rate Wide dynamic range Analog output Yellow-Green light source 570nm Compact size 13mm x 19mm x 70mm Low power Light weight
3.0 Functional Description
The AMIS-710404-A8 imaging array consists of 7 sensors, which are cascaded to provide 896 photo-detectors 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 of the AMIS-710404-A8 module. Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing which has a cover glass, which acts 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 (see Figure 4). The cross section of the AMIS-710404-A8 is shown in Figure 1 and the block diagram in Figure 2.

Tint: line scanning rate or integration time. Tint is determined by the interval between two start pulses (SP). f: main clock frequency also equals the video sampling frequency. Video output level is controlled with an adjustment as well as integration time. Up = {[Vp(max) -Vp(min)]/Vp(max)}x100% Where VP(max) = maximum peak pixel and VP(min) = minimum pixel. Ud = Vdmax - Vdmin Vdmin is the minimum output voltage with LED off. Vdmax is maximum output voltage with LED off. This level is measured from the reset level, which is located between the pixels, during the pixel reset duration. The reset level is at ground, 0V. It can be adjusted with the offset potentiometer located on the module. MTF = [(Vp(n) - Vp(n+1)] / (Vp(n)+ Vp(n+1)] x 100 [%] Vp(n): nth maximum output pixel from a 4.0 lp/mm target. V(n+1): (n+1)th minimum output pixel from a 4.0 lp/mm target. lp / mm: line pair per mm

8.0 Switching Characteristics (25C)
Data Sheet
Figure 3: Module Timing Diagram
The switching characteristics (25C) for the I/O clocks are shown in Figure 3. For the timing symbol definitions see Table 6.
Table 6: Timing Symbol's Definition and Timing Values Item Symbol Clock cycle time to Clock pulse width tw Clock duty cycle (1) Prohibit crossing time of SP tprh Data setup time tds Data hold time tdh Signal delay time tdl Signal settling time tsh
Note: (1) "Prohibit crossing of start pulse" is to indicate that the start pulse should not be active high between any two consecutive high going clock pulses or two consecutive low going clock pulses (see Figure 3). Only one high going clock under the active high start pulse initiates the internal shift register, and it must not be active over two high going clocks. All low going clock pulses will not initiate the shift register but to ensure that the start pulse will not be actively high during two consecutive high going clocks, the circuit should be designed to keep the start pulse active only for one low going clock cycle.

9.0 Mechanical Structure of the Module
Data Sheet
An isometric overview drawing of the AMIS-710404-A8 module's housing is shown in Figure 4. These modules are supplied with plastic end caps. However, for a more compact installation the end caps can be removed, provided that the modules are kept in the dark with no external light leakage allowed inside the housing.
Figure 4: AMIS-710404-A8 Module Housing
Although the standard module comes with connector pins extruding to the sides as shown, a straight pinned socket can be installed into the PCB with its pins extruding directly up from its mount PCB. However, this must be requested upon ordering of the modules, otherwise the standard configuration will be shipped. For module design-in, a detailed drawing is available upon request.
