ADNS-3090
High-Performance Optical Mouse Sensor
Data Sheet
Description
The ADNS-3090 is a high performance addition to Avago
Technologies’ popular ADNS family of optical mouse
sensors.
The ADNS-3090 is based on a new, faster architecture with
improved navigation. The sensor is capable of sensing high
speed mouse motion - up to 6 0 inches per second and
acceleration up to 2 0g – for increased user precision and
smoothness.
The ADNS-3090 along with the ADNS-2120-001 trim lens,
ADNS-2220-001 assembly clip and HLMP-ED80-XX000 form
a complete, compact optical mouse tracking system. There
are no moving parts, which means high reliability and less
maintenance for the end user. In addition, precision optical
alignment is not required, facilitating high volume assembly.
The sensor is programmed via registers through a four-wire
serial port. It is packaged in a 20-pin staggered dual inline
package (DIP).
Theory of Operation
The ADNS-3090 is based on Optical Navigation Technol-
ogy, which measur es changes in position b y optically
acquiring sequential surface images (frames) and math-
ematically determining the dir ection and mag nitude of
movement.
It contains an I mage Acquisition System (IAS), a Dig ital
Signal Processor (DSP), and a four-wire serial port.
The IAS acquires microscopic surface images via the lens
and illumination sy stem. These images ar e pr ocessed
by the DSP t o determine the dir ection and distanc e of
motion. The DSP calculat es the Δx and Δy r elative dis-
placement values.
An external microcontroller reads the Δx and Δy informa-
tion from the sensor serial port. The microcontroller then
translates the data into PS2 or USB signals before sending
them to the host PC or game console.
