ADVANCE INFORMATION
LM9638 Monochrome CMOS Image Sensor SXGA 18 FPS
General Description
The LM9638 is a high performance, low power, 1/2" SXGA
CMOS Active Pixel Sensor capable of capturing monochrome
still or motion images and converting them to a digital data
stream.
Mega-pixel class image quality is achieved by integrating a high
performance analog signal processor comprising of a high
speed 10 bit A/D convertor, fixed pattern noise elimination cir-
cuits and a programmable gain amplifier. The offset and black
level can be automatically adjusted on chip using a full loop
black level compensation circuit.
Furthermore, a programmable smart timing and control circuit
allowing the user maximum flexibility in adjusting integration
time, active window size, gain, frame rate. Various control, tim-
ing and power modes are also provided.
