1. General description

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).

5-4. Timing and state diagrams

5-4-1. Quadrature Output Waveform

The output signals are two channels quadrature (△X and △Y), which emulates encoder

phototransistors. Sensor IC generates △X and △Y relative displacement values that are converted into two channel quadrature signals. The two channel quadrature outputs are 3.5V signals. The △X and △Y counts are used to generate the X1, X2 and Y1, Y2 quadrature signals. The quadrature signals can change at a maximum rate of 25 KHz. The following diagrams show the timing for positive X motion, to the right direction.

X2 X1 t t t t t t where t = 40us
