Laser navigation sensor with integrated Bluetooth from Avago for wireless mouse applications

Avago has made available the ADNS-7630 Bluetooth (BT) 2.1 LaserStream System-on-Chip (SoC) navigation sensor for wireless mouse applications. It is the company's first laser navigation sensor to integrate a BT 2.1 transceiver, stand-alone baseband processor and VCSEL surface illuminator into a single package. Laser based mice track more reliably than LED based mice.

Avago's LaserStream technology provides precise high-speed tracking on virtually all surfaces. The ADNS-7630 based mice feature high-speed motion detection of up to 30 inches per second (ips) and 8 g acceleration detection. Laser power on all ADNS-7630 devices is pre-calibrated in Avago's factory to meet IEC/EN60825-1 Class 1 Eye Safety standards.

The ADNS-7630 device contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), Bluetooth HID (Human Interface Device) stream output and RF transceiver. Images acquired by the IAS are processed by the DSP to determine the direction and distance of motion. The DSP generates the ?x and ?y relative displacement values which are then converted for wireless transmission to the Bluetooth host. All these processes are automatically executed by the ADNS-7630 without the mouse manufacturer being involved with source code or firmware.

This SoC BT navigation engine has a fully synchronized BT navigation core and baseband circuitry. All communication and algorithms involved between the laser light sensor and RF stages have been optimized for the application.

The ADNS-7630 device supports multiple I/Os which can be configured as buttons and LED indicators. Each button can be programmed to have several functions, depending on if it is clicked once, double-clicked, or long-pressed. Button functions include KeyMap for keyboard shortcut keys, media buttons for audio control, and mouse resolution increase/decrease/rotate features.

The ADNS-7630 product also supports both mechanical and optical z-wheel and tilt-wheel functions, programmable resolution, 4-axis sensor rotation and configurable low power operating modes for extended battery life.

Avago's free MConfig software gives manufacturers the ability to store configuration settings in an external 128 kbit EEPROM so that a diverse range of markets can be served by one basic ADNS-7630 design.
