1. DESCRIPTION
This data sheet covers the PI616MC-AS specification and brief description of the PI616MC-AS
CIS Module.
CIS stands for Contact Image Sensor. It is a one-dimension array of photosensitive elements,
designed to image documents with a one-to-one magnification ratio. The sensors are
sequentially cascaded to form a one dimensional variable-length line array in multiple integral
numbers. Hence, providing the users desired lengths.
The PI616MC-AS is one of these special length line-image arrays. It is configured with a total of
8 sub sections, each section containing a sequential line of 5 array sensors with its individual
video output line. These 8 video outputs, are also referred to as tapped outputs. They are all
readout in parallel. See Figure 1, Simplified Circuit Block Diagram. The 8 sub sections are all
sequentially cascaded to form the one-dimensional array. It is fabricated on two PCB (Printed
Circuit Board) referred to as sensor boards. Each sensor board contains 4 sub sections. The
two sensor boards are cascaded in series to form a complete line image sensor of 8 sub sections
with a total read length of @ 325mm. Accordingly, each sensor board contains 20 each of PI3039
image sensors, also a product of PIC. Hence, for both boards there are a total of 8 parallel
tapped outputs and 40 each of the PI3039 image array sensors. Each chip has 192 photo
sensing cells, hence, on one board there are 3840 cell sites and a total of 7680 cell sites for both
board. Each cell site is a photo-detector that possesses its own independent processing circuit.
An associated on-chip digital shift register scans and reads each photo detector’s video signal on
to a common output video line. In section of 5 sensors these common output video lines are
individually brought out to the sensor boards’ I/O connectors. There are two connectors, one on
each board, each with four video outputs. These connectors are connected via a cable to their
respective amplifier boards. See Figure 2, System Configuration Block Diagram. PI616MC-AS’s
schematic and its PCB mechanical outline drawing are attached to this data sheet.
2. OVERVIEW
The PI616MC-AS has » 324.2 mm read width. Its recommended line rate is 192ms/line @
5.0MHz clock rate, but its minimum can be low as 160ms/line @ it’s maximum clocking speed of
6.0 MHz. Its sensor photo-site density is 23.25 elements/mm. See Peripheral Imaging
Corporation’s PI3039 data sheet that covers the specifications on the imaging array sensor.
Operationally, it requires only the power supplies, +5V and –5V and two input clocks, one is the
clock, CP, to operate the internal shift registers, second is the start pulse, SP, to initiate the
output scan.

Notes:
Note (1) Vpavg is a symbol representing the average value of every pixel in the complete line
scan. Vp(n) is the pixel amplitude of nth pixel in a line scan. This measurement is taken
with the image array under a uniform light exposure. The typical output is specified with
a uniform input light exposure of 0.5mJ/cm2 from a blue Led light source.
Note (2) Two saturated video output levels are specified. One is at the video signal’s output
amplifier, VSATA, and the other is at the input of the amplifier. In almost all
applications, because the integration time is usually too short, there is not enough
exposure time to saturate the array sensors. Accordingly, each output amplifier is fixed
with a gain of @ 4.5.
Note (3) FREQ is generally fixed for any application for the following reasons: One is the
exposure time. With a given light power, the exposure time of the sensor depends on
integration time, TINT, and in many of the applications it uses a clock count down
circuits to generate the SP, shift register start pulse, hence, it will be related to the clock
frequency. The second is the shape of the video output pulse. Because of the output
video is in pulse charge packets, the signals are processed on the output video line of
the sensors. Hence, the signal shape depends greatly upon the amplifier
configurations. Please refer to the referenced PI3039 Data Sheet. It has some brief
outline application notes. Under Note 6 in page 6 there is a discussion on video pulse
shapes. On page 8, 9 and 10 there are discussions on the three types of signal output
stages.
Note (4) DUTY is the ratio of the clock’s pulse width over its pulse period. Because the video
pixel output resets during the clock pulse’s high period and because the reset requires
a finite resetting time, the clock duty cycle is recommended to operate within the
following limits. See referenced data sheet in above note 3. Noting that the larger the
DUTY, the less the signal amplitude, while too short of clock pulse will not provide
enough video reset time and leaves residual charges, the recommended DUTY is 25%
for frequencies < 5MHz and 50% for frequencies > 5MHz.
Note (5) TINT is determined by time interval between two start pulses, SP. Hence, if SP is
generated from a clock count down circuit, it will be directly proportional to clock
frequency. And it will be synchronous with the clock frequency. The longest integration
time is determined by the degree of leakage current degradation that can be tolerated
by the system. A 10ms maximum is a typical rule-of-thumb. An experienced CIS user
can use his discretion and determine the desired tolerance level for the given system.
PAGE 4 OF 22 - PI616MC-AS, 12/20/02
Note (6) TOP is a conservative engineering estimate. It is based on measurements of similar CIS
modules and simple bench top tests using heat guns and freeze sprays. These will be
re-measured during the pilot production under the standard QA practices that is under
control of ISO 9000.

Notes:
1. TINT is the line-scan rate or integration time. It is determined by time interval between
two start pulses, SP. Hence, if SP is generated from a clock count down circuit, it will be
directly proportional to clock frequency. And it will be synchronous with the clock
frequency. The longest integration time is determined by the degree of leakage current
degradation that can be tolerated by the system. A 10ms maximum is a typical rule-ofthumb. An experienced CIS user can use his discretion and determine the desired
tolerance level for the given system.
2. FREQ is clock frequency, also equal to the signal data rate. It is generally fixed for
many applications for following reasons: One is the exposure time. With a give light
power, the exposure time of the sensor depends on integration time and in most
applications it uses clock count down circuits to generate the SP, shift register start
pulse. The second is the shape of the video output pulse. Because of the output is in
pulse packets of video charges, the signal are processed on the output video line of the
sensors. The signal shape depends greatly upon the amplifier configurations. Please
refer to the referenced PI3039 Data Sheet. It has some brief outline application notes.
Under Note 6 in page 6 there is a discussion on video pulse shapes. On page 8, 9 and
10 there are discussions on the three types of signal output stages.
3. The RESPONSIVITY is the ratio of video signal in volts divided by the unit exposure
(Volts/micro-Joules/cm 2). This exposure was measured with the output level adjusted
to 1.27V. The spread of the measured exposure R-RSP, G-RSP and B-RSP can be
used to compute the user’s desired signal voltage level.
Since this is prototype module, all of the following notes 4, 5, 6, 7 and 8, are on data, based on
engineering scope measurements, the data will be re-measured during pilot production using all
the standard QA practices under the control of ISO 9000 regulations. Furthermore, they will be
taken on fully computerized test systems. If required, these prototype data may be revised.

Vpmax = maximum pixel value of Vp(n); Vpmin = minimum pixel value of Vp(n); Vpavg =
å Vp(n)/7680; where Vp(n) is the nth pixel in a line scan with the module scanning a
uniform white target. Vp values are measured with a uniform exposure.
BRIGHT OUTPUT NONUNIFORMITY: Up(+) = [(Vpmax - Vpavg) / Vpavg] x 100% or
Up(-)= [(Vpavg - Vpmin) / Vpavg] x 100%, whichever polarity with the highest value is
selected. Two further notes, one is that the PI616MC-AS has no requirement for an
optical system, or a light system. The second is that the non-uniformity is dominated by
the LED light bar’s non-uniformity so only the sensor non-uniformity is specified. The
normal standard CIS modules are enclosed in a self-contained module with the
complete optical and LED lighting system. So the light system, usually LED bar, is
included in making the measurement of the optical characteristics. This fixes the optical
geometry for the module and the light source. So the module’s optical characteristics
are simply measured with the module placed on a uniform reflecting target with a know
reflection density. However, the PI616MC-AS is not enclosed with its optical and light
source system. So Up is measured with uniform light source that directly illuminates the
image sensors’ photosite.
ADJACENT PIXEL NONUNIFORMITY: Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x
100%. Upadj is non-uniformity in percentage of Vpavg. It is the maximum difference
amplitude between two neighboring pixels.
BRIGHT OUTPUT TOTAL NONUNIFORMITY: Uptotal = [Vpmax -Vpmin]/Vpavg
DARK NONUNIFORMITY: Ud = Vdmax – Vdmin: It is measured over the full length of
the array with the light source off and the sensors are placed in the dark. Vdmax is the
maximum pixel value of the video pixel with the exposure off. Vdmin is the minimum
PAGE 6 OF 22 - PI616MC-AS, 12/20/02
pixel value of the video pixel with exposure off. The references for these levels are the
dark level, VDL.
9. DARK OUTPUT VOLTAGE, VDL is the level between the out video pixel dark level and
the ground.
10. RANDOM NOISE, RNL, is measured using two methods, one is tangentially on the
scope. This measures an approximate peak-to-peak, p-p, random thermal noise. The
other is in terms of rms. It is estimated by using the Gaussian Statistical Methods. One
pixel is selected out of a line scan and its peak values are recorded for a multiple line
scans. These random peak values are used to estimate the rms values.
11. MODULATION TRANSFER FUNCTION depends on the optical system. Since this
system relies on the users optical system it was not measured. Refer back to note 5,
measurements on Up, all notes that references the optical measurements applies to
MTF measurements as well. Using a conservative engineering estimate, the sensor’s
MTF is in excess of 70% at the Optical Nyquest Frequency.

9.0 I/O CONNECTOR PIN CONFIGURATION
There are two I/0 connectors on the stiffener plate with the two sensor boards. They are MOLEX
52610-1590. They serve to interconnect the sensor boards to the amplifier boards. See the
outline drawing of the system, Figure 2, System Configuration Block Diagram. Two 15
conductors strip lines serve as the interfacing harness. It is depicted with harnesses coming
from under the stiffener plate and crossing to the top of the amplifier board and connecting to the
two input connectors MOLEX 52207-1950. The final connectors are the two ERNI-594083. They
are the SYSTEM I/Os.
TABLE 9.1A SENSOR BOARD CONNECTORS AND INPUT CONNECTORS FOR

TABLE 9.1B AMPLIFIER BOARD OUTPUT CONNECTORS, ERNI-594083
There are four connectors on the amplifier board. Two are inputs, which are described
above, and two are outputs, which are described below. There is only one table shown for
both connectors. They are both identical in there connections except one is for sensor
board 1’s outputs and the other is for sensor board 2’s outputs. Accordingly each of the
video outputs, after amplification, for both sensor boards are labeled VOUT1, VOUT2,
VOUT3 and VOUT4. Videos from sensor board 1, VSEC1’s corresponding output is
VOUT1, VSEC2’s corresponding output is VOUT2, VSEC3’s corresponding output is
VOUT3 and VSEC4’s corresponding output is VOUT4. Then the videos from sensor board
2 will have their corresponding outputs on the second connector VOUT1, VOUT2, VOUT3
and VOUT4, except they are outputs VOUT5, VOUT6. VOUT7 and VOUT8 because their
video signals originate from section 5, section 6, section 7 and section 8 of the sensor

PAGE 10 OF 22 - PI616MC-AS, 12/20/02
10.0 SCHEMATIC DIAGRAM
Two reference schematic diagrams are attached. Only one schematic, CKT 1, Sensor Board
Schematic, is required to represent both the sensor board 1 and 2 because the circuits are
identical. The second one is for the amplifier board it contains all eight of the amplifiers on one
schematic. The circuit description of its structure and operation has been briefly discussed in
section 1, DISCRIPTION, page 2. Its operation follows from the discussion of the simplified block
diagram. There are only two input control clocks for the circuits, the clock, CP, and the start
pulse, SP. SP starts the shift register scanning while CP clocks the register and produces the
video pixels at its same rate. The clocks are entered through the I/O connectors on both sensor
boards. They are both externally buffered with the 74HC00 hexes and applied to inputs of the
image sensors. On each of the two-image array sensor boards there are four sequential video
sections. Each video section contains a row of 5 sequential image array sensors, PI3039. These
are all clock in parallel with CP. The four sections on both boards are clocked with SP in parallel
to initiate all eight video sections and simultaneously begin the eight sequential readouts. All
eight lines, four in each sensor board, have reset switches, BU4S66, that parallel resets the
video pixel charges after they are readout. These pixels, readout in parallel, are applied to their
respective output amplifiers on the amplifier board.
The second schematic, CKT 2, Amplifier Board Schematic, is the amplifier board. There are eight
amplifiers for processing the output videos from both sensor boards. The amplifier board
receives the inputs from sensor board output connector, J1, through two harnesses. They are
connected into the input I/O connectors, J1 and J2, of the amplifier board. Since there are two
sensor boards using the same schematic representation, the connector on sensor board 1, J1,
becomes J2 for the second board. They are physically differentiated and marked as J1 and J2
on the Stiffener Board. Since all eight sections process their video signals through identical
amplifiers, only one amplifier circuit is discussed. The AD8051 is an operational amplifier that is
configured into non-inverting buffer amplifier with again of @ 4.5. It is used to isolate the video line
from its external circuits. The isolated video line then serves as a storage capacitance for the
pixels outputs. The pixel charges are read out onto the video line capacitance and integrated.
This integrated pixel charges, converted to a voltage pulse, is amplified and produced at the
output I/O. The reset switch on the video line, which is located on the sensor board schematic,
resets the pixel signal charge prior to the readout of following pixel.
11.0 DRAWING ON MECHANICAL STRUCTURE
Attached are 6 mechanical drawings. The first one, Top Assemble Outline, sheet 1of 1,
shows an outline drawing of the complete CIS system, consisting of the Stiffener Plate, the
interconnecting harness and the Amplifier Board. There are two connector Pin
Configuration Tables, one for the two sensor boards and the input for the amplifier board.
The other is for the two output connectors on the amplifier boards. These two tables show
the pin numbering and names for the 6 connectors that are seen in the drawing. For detail
descriptions of the interconnection and their functions, see section 9.0 CONNECTORS PIN
CONFIGURATION, page 9.
