NOM02A6-AR25G
200 DPI High-Speed Contact
Image Sensor Module
Description
The NOM02A6−AR25G contact image sensor (CIS) module
integrates a red LED light source, lens and image sensor in a compact
housing. The module is designed for document scanning, mark
reading, gaming and office automation equipment applications and is
suitable for scanning documents up to 104 mm wide. An analog video
output achieves a scanning rate of 167
m
sec/line. The
NOM02A6−AR25G module employs proprietary CMOS image
sensing technology from ON Semiconductor to achieve high−speed
performance and high sensitivity.

V
LED
directly affects illumination intensity, which in conjunction with the LED timing and integration time, directly affects V
OUT
.
T
int
is the line scanning rate or integration time. T
int
is determined by the interval between two start pulses. The clock is proportional to T
int
.
Main clock frequency (f) corresponds to the video sampling frequency.
Min, Typ, Max specifications reflect operation at the corresponding Min, Typ, Max clock frequency.
Prohibit crossing time is to insure that two start pulses are not supplied in the same scan line time. SP may only be active high during one
falling edge of CP for any given scan.
