Data Sheet
1.0 General Description
The AMIS-710627-A4 (PI627MC-A4), AMIS-710628-A4 (PI628MC-A4) and AMIS-710629-A4 (PI629MC-A4) are a family of contact image sensor (CIS) modules, using MOS image sensor technology for high-speed performance and high sensitivity. They contain a complete optical imaging system that includes the light source and focusing elements. The modules' contact image sensor is divided into four sections, each with its own video output and identical processing circuits allowing for high scanning speeds. Each module comes with its own particular LED light source, which have different maximum light power outputs. Since the light power limits the exposure, which is proportional to the product of scanning speed and light power, each module will have a different maximum scanning speed and signal output voltage. The modules can be used for scanning A4 size (216mm) documents with 23.62 dots per millimeter (dpm) resolution. Applications include document scanning, mark readers, gaming, and office automation equipment.

3.0 Functional Description
Each of the three modules consists of 27 AMIS-720639 (PI3039) image sensors cascaded together. Each sensor consists of 192 photo-sensing elements (pixels), resulting in a module 5184 pixels long. These image sensors have associated multiplex switches that are sequentially accessed with its digital shift register. In addition, each has a chip-select switch that functions to activate its preceding sensor on the cascaded sequence, after its predecessor chip has completed its scan. The start pulse initiates the shift register of the first chip in all four sections. The first chip then sequentially clocks out the integrated image charge from each pixel. These charges are passed through the sensors' multiplexing switch and then out onto the video line, where they are converted to a voltage. When the sensor completes its scan, the chip-select switch on the following chip is switched on to continue the line scan until it completes its scan in one section. A new scan is initiated when a start pulse is again entered into the first chip of each section. The 27 sensors are cascaded together and bonded onto a PCB. The cascaded sensors are then divided into four subsections, each subsection having its own output. The first three subsections contain seven sensors and the fourth contains six sensors. Each output is then connected to its own video line. The four video lines form a video line capacitance, which are buffered by video amplifiers, to act as output drivers. The charge from each output is integrated onto the video line capacitance and readout. Each pixel is then reset and ready to integrate again. Mounted in the module is a one-to-one graded indexed micro lens array that focuses the scanned documents to be imaged onto its sensing plane. Illumination is by means of an integrated LED light source. The particular LED for each module is listed in Table 1.

Tint is the line-scanning rate or integration time and is determined by the interval between two start pulses, SP. The integration time listed for each module is the minimum integration time required to give 0.5V output at each modules maximum clock frequency. Fclk is the main clock frequency, also equals the pixel rate. Video output level is dependent on the integration time and LED light power. Up = [Vp(max) - Vpavg] / Vpavg x 100% or [Vpavg - Vp(min)] / Vpavg} x 100%, whichever is greater, where Vp(max) = maximum pixel level, Vp(min) = minimum pixel level, and Vpavg = average of all pixels. Adjacent photo-response non-uniformity (Upn). Upn = Max ((Vpn - Vpn+1) / Min (Vpn, Vpn+1)) x 100%, where Vpn is the pixel output voltage of pixel n in the light. Ud = Vdmax - Vdmin, where Vdmin is the minimum output voltage with LED off and Vdmax is maximum output voltage with LED on. See the paragraph under Reset Level and Video Sampling Time for explanation. See the paragraph under Depth of Focus. A graph of the typical MTF vs. Depth of Focus is shown.

Note: 1.
The maximum clock speed is limited by the modules light source power, due to the low light power associated with LED's. The minimum clock speed is determined by the longest tolerable integration time. Because of the leakage current build up, the integration time is recommended to be no greater than 10ms.

9.0 Reset Level and Video Sampling Time
Figure 3: Reset Level and Sample Time
Figure 3 shows the video signal waveform and details a single pixel. The signal output waveform is shown referenced to the input clock waveform. Also shown is the terminology used to define the dark and bright output levels and the recommended pixels sampling times. The dark level is defined by using the module imaging on a black target or with the light source turned off. The dark level is then measured from ground or 0V. The reset level is a reference level of the reset switch, which is not necessarily at ground. The reason for this is that after the reset operation, the video signal is passed through an amplifier, which may have some offsets. The difference between the dark level and reset level is called the pedestal, PED. Hence, the reset level will sit below the dark level. The video pixels, demonstrated in this graph, are ideal waveforms from a CIS module using a phototransistor imaging structure. The video output at high speeds, such as 5.0MHz, does not instantly rise to its final value, although, if it is given enough time it would eventually approach its steady state value (in order of milliseconds). However, at high speeds it is impractical to wait until a final stable value is reached. The suggested sampling point is therefore a few nanoseconds prior to the signal falling edge.

10.0 Depth of Focus
Figure 4 shows the typical MTF versus Distance, which can be used to define the working depth of focus. Two curves indicate the spread among the modules. Note that the MTF is greater than 40 percent out to a distance greater than 0.3mm from the glass surface. Since this module is a 600dpi module, a pixel density of 600 pixels per inch, the MTF was measured with a 300dpi or a 150 line-pair per inch optical bar pattern. The test was conducted with pixel rate set to 5.0MHz. The effective algorithm used in the measurements is as described by the following equation: MTF={[Vp(n)+Vp(n+1)]/2-[Vp(n+2)+Vp(n+3)]/2}/{[Vp(n)+Vp(n+1)]/2+[Vp(n+2)+Vp(n+3)]/2} th th Where n is 1, 2, .....5184 , Vp(n) is the signal amplitude of the n pixel.

11.0 Timing Characteristics at 25C
The timing characteristics at 25C for the I/O clocks are shown in Figure 5 and their definitions detailed in Table 12. Only one video output is shown because all four video sections have identical electrical characteristics. Since there are seven die in sections one, two and three and six die in Section 4, the output waveform for Section 4 (Vout 4) is shorter by 192 pixels.

"Prohibit crossing of the start pulse", tprh, is to indicate that the start pulse should not be active high between two consecutive low going clock pulses. All falling clock edges under an active high start pulse loads the internal shift register, therefore the start pulse must be active over only one falling clock edge. A high start pulse crossing over any rising clock edges are ignored by the shift register. One simple way to ensure that the start pulse will not be actively high for any two consecutive falling clock edges is to generate the start pulse on a rising clock edge and terminate it on the following rising clock edge.
