Low Power LED Gaming Mouse Sensor
PMW3310DH-AWQT low power gaming sensor is a new addition to
PixArt Imaging’s gaming sensor family. The tracking system comprises
of navigation IC, HSDL-4261 IR LED and lens. It provides enhanced
features such as variable frame rate, programmable resolution, angle
tunability, X-Y axis independent resolution, programmable angle snap
plus configurable sleep and wake up time to suit various gamers’
This gaming sensor is in a 20-pin staggered dual in- line package (DIP).
It is designed to be used with ADNS-2120-001 trim lens to achieve
optimum performance featured in this document.
Theory of Operation
The sensor measures changes in position by optically acquiring
sequential surface images (frames) and mathematically determining the
direction and magnitude of movement. It contains an Image Acquisition
System (IAS), a Digital Signal Processor (DSP), and a four wire serial
port. The IAS acquires microscopic surface images via the lens and
illumination system. These images are processed by the DSP to
determine the direction and distance of motion. The DSP calculates the
Δx and Δy relative displacement values. An external microcontroller
reads the Δx and Δy information from the sensor serial port. The
microcontroller then translates the data into PS2, USB, or RF signals
before sending them to the host PC or game console.
