ADNB-3552
Low Power LED Integrated Slim Mouse Sensor
Data Sheet
Description
The ADNB-3552 LED mouse bundle is a small form
factor (SFF) LED illuminated navigation system. The
bundle consists of an integrated chip-on-board (COB)
LED mouse sensor ADNS-3550 and a SFF lens ADNS-
3150-001.
The ADNS-3550 is a low-power optical navigation sen-
sor. It has a new, low-power architecture and automatic
power management modes, making it ideal for battery-
and power-sensitive applications such as cordless input
devices.
The ADNS-3550 is capable of high-speed motion detec-
tion — up to 20 ips and 8 G. In addition, it has an on-
chip oscillator and integrated LED to minimize external
components.
The ADNS-3550, along with the ADNS-3150-001 lens,
form a complete and compact mouse tracking system.
There are no moving parts which means high reliabil-
ity and less maintenance for the end user. In addition,
precision optical alignment is not required, facilitating
high volume assembly.
The bundle sensor is programmed via registers through
a four-wire serial port. It is packaged in a 16 I/O surface
mountable package.
Theory of Operation
The ADNS-3550 is based on Optical Navigation Technol-
ogy, which measures changes in position by optically
acquiring sequential surface images (frames) and math-
ematically determining the direction and magnitude of
movement.
The ADNS-3550 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
Dx and Dy relative dis-
placement values.
An external microcontroller reads the
Dx and Dy infor-
mation 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.
