ADNS-7700
One chip USB LaserStream™ Mouse Sensors
Data Sheet
Description
The ADNS-7700 series are compact, low cost, one chip USB
LaserStreamTM mouse sensors designed for implemention
of a non-mechanical tracking engine in computer mice.
This ADNS-7700 sensor is a 22-pin integrated molded
lead-frame DIP package. It comprises a USB controller
and LaserStream navigation sensor with VCSEL integrated
within a single package. It is designed to be used with the
ADNS-6180-001 trim lens or ADNS-6180-002 wide trim
lens to achieve the LaserStream performance featured
in this document. These parts provide a complete and
compact navigation system with no moving parts and
precision optical alignment to facilitate high volume as-
sembly. Avago has pre-calibrated the laser power prior
shipment, thus NO laser power calibration is required at
manufacturer site, therefore reducing assembly time and
associated cost.
The motion output is a selectable 8/12/16-bit USB data re-
porting format. This device is compliant to USB Revision
2.0 low speed specification. The ADNS-7700 series are
designed with on-chip One-Time-Programmable (OTP)
memory. This enables device configuration flexibility for
the manufacturer to cater for various market segments.
Theory of Operation
The ADNS-7700 is based on Laser-Stream navigation tech-
nology that measures changes in position by optically ac-
quiring sequential surface images (per frames) and math-
ematically determining the direction and magnitude of
motion movement.
It contains an Image Acquisition System (IAS), a Digital
Signal Processor (DSP) and USB stream output. The IAS
acquires microscopic surface images via the lens. These
images are processed by the DSP to determine the direc-
tion and distance of motion. The DSP generates the x
and y relative displacement values which are converted
to USB motion data.
