OM02,Mouse IC, Integrated Circuit

This optical CMOS sensor provides a non-mechanical tracking engine for implementing a computer
mouse. On the CMOS IC chip, images are captured, digitized, and then digitally processed.
Using an optical navigation technology, the sensor measures changes in position by optically
acquiring sequential surface images (frames) and mathematically determining the direction and
magnitude of movement. The sensor is mounted in a plastic optical package and is designed to be
used with a high intensity LED. Hence, it provides a complete and compact tracking engine. This
optical tracking engine has no moving parts and requires no precise optical alignment. Thus, it
enables high volume system assembly. It offers a quadrature output mode for interface flexibility.
The tracking resolution is specified at 400 counts per inch (cpi) at rates of motion up to 16 inches per
second (ips).
