ADNS-7700

One chip USB LaserStream™ Mouse Sensors

Data Sheet

Description

The ADNS-7700 series are compact, low cost, one chip USB

LaserStream

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.
