ATA2180AF/ATA2180EF/ATA2180LF/ATA2180ELF:The ATA2180 is an optical sensor with capability of replacing current track ball mouse of computer system. How the most common optical sensor for mouse works today is: The sensor captures "snapshots" of the work surface at 1,700 times per second, calculates ±3-pixel movement per frame, and produce 5,100 pixel movements per second with internal 6MHz oscillator. With internal 12MHz oscillator, the sensor captures snapshots of the work surface at 3,400 times per second, calculates ± 3-pixel movement per frame, and produce 10,200 pixel movements per second.
