AMIS-710414-A4: 400dpi CIS Module
Four Parallel Video Outputs for RED + IR Light Source
Data Sheet
1.0 General Description
The AMIS-710414-A4 (PI414MC-A4-R) is a contact image sensor (CIS) module, which uses MOS image sensor technology for highspeed performance and high sensitivity. The AMIS-710414-A4 is suitable for scanning A4 size (216mm) documents with 15.8 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 15.8dpm resolution, 216mm scanning length Dual LED light source, RED and IR, with a line scan time to 180sec @ 5MHz Wide dynamic range Analog output Compact size 14.0mm x 19.5mm x 232mm Low power Light weight
3.0 Functional Description
The AMIS-710414-A4 imaging array consists of 27 AMIS-720642 (PI3042) sensors, produced by AMI Semiconductor, which are cascaded to provide 3456 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 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-710414-A4 module. These 27 sensors bonded on a printed circuit board (PCB) are grouped into four sub-cascaded sections. Each contiguously cascaded chip section is connected on separate video lines, accordingly providing four video outputs, VOUT1, VOUT2, VOUT3, and VOUT4. Before the signal charges from the four video lines appear at their respective outputs, they are converted to signal voltages by four on-board buffer amplifiers; one for each of its corresponding video sections. The first three sections, VOUT1, VOUT2 and VOUT3 have seven sensor chips, while the VOUT4 has six sensor chips. Since each sensor chip has 128 pixels, there are a total of 3456 pixels (see Figure 1). Illumination is accomplished by means of integrated LED sources; Red (65nm) 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 facilitated by a 12-pin connector, EBW-PK23-P012L2-3Z, located on one end of the module. For the location of Pin 1, see Figure 4. The cross section of the AMIS-710414-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 180sec is set at the factory. For additional comments, see Note 1 under Table 5. fclk: main clock frequency Vpavg = Vp(n)/3456 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: is the maximum output voltage on a black document (LED is turned off). MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%] Vmax: is the maximum output voltage at 100lp/in (200dpi target) and Vmin: is the minimum output voltage at 100lp/in (200dpi target), where lp / in is the line pairs per inch.

9.0 Switching Characteristics (25C)
The switching characteristics (at 25C) for the I/O clocks are shown in Figure 4. For the timing symbol definitions, see Table 6.
Figure 3: Timing Diagram
Note: Only one video output is shown because all four videos have identical electrical characteristics. The only physical difference between outputs is in the Section 4 output, VOUT4. Section 4 has only six sensor chips, hence its active scan is shorter by 128 pixels.

"Prohibit crossing of start pulse" is to indicate that the start pulse should not be active high between any two consecutive high going clock pulse 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. 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 high going clock cycle.
