AMIS-710205-A4/AMIS-710206-A4: 200dpi CIS Modules Data Sheet
1.0 General Description
The AMIS-710205-A4 (PI205 MC-A4-R) and AMIS-710206- A4 (PI206MC- A4-R) are a fa mily of contact image sensor ( CIS) modules. As
a family group they are called AMIS-710205/206 modules. They are long contact image sensor modules, using MOS image sensor
technology for high-speed performance an d high sensitivity. They contain their o wn complete optical system including the light source;
accordingly, they make a very compact imagi ng s ystem. The four paralle l video outp uts give this family of CIS modules their hig h speed
performance. They all possess identical electrical circuit compon ents, as well as the same mechanical and optical c omponents, except
for their LED light so urces. They differ in their s pecification, ho wever, because the different l ight sources im pact the efficacy of t he high
speed performance.
The two modules are suitable for scanning A4 size (216mm) documents with eight dots per millimeter (dpm) resolution. Applications
include document scanning, mark readers, gaming and office automatio n equipment.

3.0 Functional Description
Each of the two modules in th e family AMIS-710205/206 consists of four major components. T he first of them is the printed circuit boar d
(PCB) on which the 27 imaging chips, AMIS-720233 (PI3033), are bonded. These sensor chips, pr oduced by AMI Semiconductor, are
monolithic devices with 64 photo sensing elements. Each of 27 chips are completely self-contained scanning chips with their control
circuits integrated within the chips, so that they can be cascaded to provide a 1728 photo-elements module. The AMIS-720233 chips
are integrated with the photo sensors' associated multiplex switches, a digital shift register and the chip selection switch. The chip's shift
register sequentially clocks out the integrated image charges from each sensing element and passes them through the chip-select
switch and out onto the video line. The chip-select switches are sequentially switched as each of the predecessor chips completes its
scan. These 27 sensors, bonded on a PCB, are gro uped into four sub-cascaded s ections. Each contiguous ly cascaded chip section is
connected on separ ate video li nes, provid ing four vi deo outputs, VOUT 1, VO UT2, VOUT 3, and VOUT4. Before the sign al charges fro m
the four video lines appear at their resp ective outputs, they are converted to signal voltages by four on-board buffer amplifiers; one for
each of its corresponding video section. The first three sections, VOUT1, VOUT2 and VOUT3 have seven sensor chips, while the
VOUT4 has six sensor chips. Since each sensor chip has 64 pixels, there are a total of 1728 p ixels (see Figure 1).
Mounted in the module housing, along with the PCB, is the second major component. It is a one-to-one graded indexed micro lens
array, which focuses the image of the scanned documents onto the sensing line of the sensor chips. The third major component
mounted in the module is the LED light source (see Figure 2). This pictorial cross section shows the LED bar light source and its
illumination path as it reflects the image from the document and focuses through the ROD lens on to the image sensing line of the
sensing chips. All components are housed in a small plastic housing and covered with the fourth major component, a glass window.
This cover glass not only s erves to protect all of the critical components within the housing from dust, but it also serves a m inor role in
the optical system. Together with rest of the module's optical system, the modu le is adjusted to obtain the optimum depth-of-focus.

9.0 Reset Level and Video Sampling Time
Figure 3: Video Pixel Definition
Figure 3 graphicall y shows the video signal waveform and defines the sing l e video pi xel structure. T he signal outp ut waveform is sho wn
relative to the input c lock waveform, as well as the symbols and termi nologies used to define the performance spec ifications. Figure 3
explains the terminology used to characterize the dark signal levels and the recommende d video pixel sampling times.
Note 6, under T able 7, specifies the dark lev el (DL). This is the level seen dur ing the dar k read out; for example, either the module sits
on a black target or the light source is turned off. It is measured from ground or 0V. The reset level is a reference level for the reset
switch, which is not necessarily on ground because after the reset occurs, the signal is passed through an amplifier. The difference
between the dark level and the reset level is called the pedestal (PED). In most cases, the offset control of the amplifier is used to
adjust the dark level to 0V or ground. Hence, the reset level will sit below ground.
The video pixels demonstrated in this graph emanate from an ideal CIS module with a phototransistor imaging structure. The video
output at high speeds, such as 5.0MHz, does not instantly rise to its final value, although given enough time; it would asymptotically
approach its steady state v alue. But, at high speeds it is im practica l to wait for the final st abl e val ue. Accordingl y, as Fi gure 3 in dicates,
the output signal continues to rise towards its steady state v alue. Consistent with the forg oing comments, und er Table 7, instead of the
conventional signal sampling time, tst is defined to substitute the conventional settling time definition. This definition is used because
the output signal continues to rise as ymptoticall y to the final stable valu e but not within a p ractical time in high speed applications. T his
is true even when the video rises to its peak value, Vp, defined in the algorithm used in t he measurements 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}
Where n is 1, 2, .....1728th, Vp(n) is the signal amplitude of the nth pixel.

Notes:

(2) This is determined by the longest tolerable integration time. Because of leakage current build up, the integration time is recommended to be no greater than 10ms.
(3) The maximum call out is for the modules' electrical speed. The light source still dictates the highest speed performance.
(4) This specification is a standard used by the CIS makers for the fax industry.

11.0 Switching Characteristics (25°C)
The switching characteristics at 25°C for the I/O clocks are shown in Figure 4. Each switch timing characteristic for each waveform is
represented by its symbolic acronym. Each corresponding switching time is defined in Table 9.
Figure 4: Module Timing Diagram
Note: Only one video output is shown because all four videos have identical electrical characteristics. The only physical difference between the outputs is in the Section 4
output, VOUT4. Section 4 has only six sensor chips; hence, its active scan is shorter by 64 pixels (see Figure 4).

Note:
(1) "Prohibit crossing of start pulse" is used to indicate that the start pulse should not be active high between any two consecutive clock pulses; specifically, between
two consecutive low going clock pulses (see the Figure 4). All falling clock edges under an active high start pulse load the internal shift register, therefore the start
pulse must be active over only one falling clock edge. A high start pulse over all rising clock edges is ignored by the shift register. One simple way to ensure that
the start pulse will not be actively high during 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.
