INTRODUCTION
Description The ATA1092XA 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 (or 3,400) times per second, then the captured images are sent to an arithmetic unit to determine direction and magnitude of movement in accordance with speed and acceleration.
However, the key differences in ATA1092XA from other optical sensors are that it is designed based on a system level architecture so that it can eliminate side parts resulting in saving extra manufacturing costs. Additionally, ATA1092XA includes Mosart's MCU (MA60H161B) within one package so that no additional MCU is needed. ATA1092XA also tolerates to all different magnitudes of movement so that the sensor can be used for design purpose where accuracy is the most important factor as well as for gaming purpose where speed would be the critical factor.
The sensor is in a 24-pin optical DIP package with external OSC pin so that the sensor can be modified to run at 12 MHz in the application. ATA1092XA comes with the "default" resolution of 400 counts per inch (cpi) and the rate of motion up to 12.75 inches per second, running at 6 MHz. Furthermore, with 12 MHz OSC, one can enhance the resolution electrically up to 600 cpi with the rate of motion up to 19 inches per second ("Fast")

OPERATIONS
Theory of Operation
LED Lens IAS Pixel Array (18 x 18) Surface Moving Calculation Numerating Focusing Photo Current Generating ADC MVF Quad. Moving Data Output ATA1080
ATA1092XA is based on Optical Navigation Technology. It contains an Image Acquisition System (IAS), a Motion Vector Finding Processor (MVFP), a two-channel quadrature output.
The IAS acquires microscopic surface images via the lens and illumination system provided by other parts. These images are processed by the MVF processor to determine the direction and distance of motion. The MVF processor generates the x and y relative displacement values that are converted into two-channel quadrature signals.
Description of Operation Once power is up, it requires 75.3 msec to be stabilized in Motion mode. In order to minimize the power consumption, when there is no motion in the sensor, ATA1092XA turns its operation into nomotion mode. That is, when there is no motion for one second (default time period) in Motion mode, ATA1092XA turns into No-Motion mode.
In default, from No-Motion mode, ATA1092XA wakes up every 10.9 msec for one report time (588 msec) and compares with the previous wake-up in order to check whether there is any movement. Likewise in fast mode (600 cpi running at 12 MHz), from No-Motion state, ATA1092XA wakes up every 5.45 msec for one report time (294 msec) and compares with the previous wake-up to check if there is any movement.
