LM9617
Monochrome
CMOS Image Sensor VGA 30 FPS
General Description
The LM9617 is a high performance, low power, third inch VGA
CMOS Active Pixel Sensor capable of capturing grey-scale digi-
tal still or motion images and converting them to a digital data
stream.
In addition to the active pixel array, an on-chip 12 bit A/D conver-
tor, fixed pattern noise elimination circuits and a video gain is
provided. Furthermore, an integrated programmable smart tim-
ing and control circuit allows the user maximum flexibility in
adjusting integration time, active window size, gain and frame
rate. Various control, timing and power modes are also provided.
