NOM02A6−AW49G
DESCRIPTION OF OPERATION
Functional Description
processed, the motor advances the paper and the next scan
line is captured.
The NOM02A6−AW49G module consists of 13 contact
image sensors, each with 64 pixel elements, that are
cascaded to provide 832 photo−detectors with their
associated multiplex switches and double−buffered digital
shift register that controls its sequential readout. A buffer
amplifies the video pixels from the image sensors and output
the analog video signal of the module as shown in Figure 2.
In operation, the sensors produce an analog image pixel
signal (or video signal) proportional to the exposure on the
corresponding picture elements on the document. The
VOUT signal outputs 832 pixels for each scan line. The first
bit shifted out from VOUT during each scan represents the
first pixel on the connector end of the module.
A pictorial of the NOM02A6−AW49G cross section view
is shown in Figure 4. Mounted in the module is a one−to−one
graded−index micro lens array that focuses the scanned
document image onto the sensing plane. Illumination is
accomplished by means of an integrated LED light source.
An internal reflector helps illuminate the document more
completely, eliminating shadows caused by wrinkles in the
paper. All components are housed in a small plastic hsing,
which has a glass cover. The top surface of the glass acas
the focal point for the object being scanned ancts th
imaging array, micro lens assembly and Lrce
from dust.

igure 5. Typical Scanner Algorithm
Figure 5 outlines the basic steps in the scanner control
sequence. Firt the circuits are initialized and the scanner
waits for a document to be detected, usually by a paper
sensing switch. Then a start pulse and clock pulse are
supplied to capture a line image. At the next clock pulse the
first pixel value appears on the output. The pixel can be
stored in a local line buffer memory. Subsequent clocks
cause the remaining pixels to be shifted out and stored in the
line buffer. Once the complete line has been shifted out it can
be transferred to the host application and the system
advances the paper and the line scan process repeats until the
paper sensing switch indicates the document has passed
completely through the scanner.

Connector Pin Out Description
Connections to the module are via a 2.4x140mm 10−pin
connector (ECE part number EBW−PK23−P010L2−3Z)
located at one end of the module as shown in the package
drawing on page 8. The location of pin number 1 is
indicated on the package drawing.
Device Marking and Barcode Description
Each module is marked with a tag that contains the part
number, a number combining the manufacturing date code
and serial number and a barcode. The barcode presents the
date code and serial number in Interleave 2 of 5 barcode
format as follows
Scanner Applications
A typical use of the NOM02A6−AW49G module in
scanner applications is shown in Figure 6. The document to
be digitized is fed into the scanner where a sensor detects its
presence. The scanner then operates the motor to move the
paper under the contact image sensor module. The module
illuminates the paper with internal LEDs and the image
sensor pixel array detects the amount of reflected light and
simultaneously measures a full line of pixels which are
sampled and transferred to a FIFO for storage and
conversion to a parallel output format. Once the pixel line is

YY is the year,

SSSSSS is the serial number.
Glass Lens Care
Precautions should be taken to avoid scratching or
touching the glass lens. The glass lens may be cleaned with
alcohol.
