in single package
LaserStream™ navigation technology
USB 2.0 Low Speed Compliance
Meets HID Revision 1.11
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 High speed motion detection at 45 inches per second
shipment, thus NO laser power calibration is required at
manufacturer site, therefore reducing assembly time and
associated cost.
(ips) and acceleration up to 20g
Input buttons: 3 or 5-buttons
Mechanical Z-Wheel interface for vertical scroll
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.
On-chip OTP memory for device configuration
flexibility without any external software driver:
– Enable/Disable Tilt-Wheel* function that supports
horizontal scroll in Microsoft Vista OS.
– 8/12/16-bit USB motion data reporting
– Resolution
Theory of Operation
Programmable from 400-2400 counts per inch (cpi)
with ~100cpi incremental step
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.
3 selections of On-the-Fly (OTF) resolution mode

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.
