AMIS-710627-A4, AMIS-710628-A4, AMIS-710629-A4:
600dpi CIS Modules
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.
2.0 Key Features
• LED light source, lens and sensor are integrated into a single module
• Ultra high-speed
• Four parallel analog video outputs, clocked as high as 5.5MHz
• 270µsec/line scanning speed @ 5.0MHz clock rate for the red light source
• 23.62dots/mm resolution, 216mm scanning length
• Wide dynamic range
• Standard A4 size ≅ 14.5mm x 19.5mm x 232mm
• Low power
• Light weight
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.
