ADNS-7050

ADNS-7050 Laser Mouse Sensor Data Sheet Description The Avago Technologies ADNS-7050 sensor along with the ADNS-6120 or ADNS-6130-001 lens, ADNS-6130-001 clip and ADNV-6340 VCSEL form a complete and laser mouse tracking system. It is the laser illuminated system enabled for cordless application. Powered by Avago Technologies LaserStreamTM technology, it can operate on many surface that proved difficult for traditional LEDbased optical navigation. It’s low power architecture is capable of sensing mouse motion while prolonging battery life, two performance areas essential in demanding cordless applications. There is no moving part, in the complete assembly for ADNS-7050 laser mouse system, thus it is high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly. Theory of Operation The ADNS-7050 is based on LaserStream™ Technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. The ADNS-7050 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 ∆x and ∆y relative displacement values. An external microcontroller reads the ∆x and ∆y infor...
