PAW3212DB-TJDT
1. Functional Block Diagram and Operation
PAW3212DB-TJDT is a high performance and ultra low power CMOS-processed optical image sensor with integrated digital image process
circuits. It is based on an optical navigation technology which measures changes in position by optically acquiring sequential surface images
(frames) and mathematically determining the speed, the direction and the magnitude of motion. The displacement delta_X and delta_Y
information are available in registers which are accessible through SPI serial interface. A host controller reads and translates the data from
the SPI serial interface into RF signals before sending them to the host PC. The word "sensor", instead of PAW3212DB-TJDT, is used in the
document.
