Avago Technologies has developed what it claims is the industry's first fully integrated and feature-rich Bluetooth 2.1 SoC LaserStream navigation sensor for wireless mouse applications, and other integrated input devices. The laser navigation sensor engine is compact, integrating a BT transceiver, stand-alone base band processor and VCSEL illumination into a single chip package. It provides a complete SoC solution that provides fast and secure connectivity and easy integration into mouse designs. It also has several features that can be configured via an external EEPROM to simplify mouse designs.

The BT 2.1 SoC laser sensor enables simple pairing for easy and secure connectivity with the BT host, as well as power savings to help extend battery life. The sensor engine was developed to meet the demands of designers who require innovative mouse sensor products that offer enhanced performance, and easy integration to help shorten their product development cycles.

In addition, Avago's SoC BT navigation engine is touted to be the first mouse sensor that is fully synched between the BT navigation core and base band. It provides tracking on virtually all surfaces and is capable of high-speed motion detection of up to 30ips and acceleration of 8g to help improve the overall end user experience. the SoC mouse sensor is also designed to support up to 10 buttons, both mechanical and optical z-wheel, and tilt-wheel functions. This BT laser sensor also meets IEC/EN60825-1 Class 1 Eye Safety standards and does not require laser calibration which helps to reduce assembly time and design cost.

The motion output of Avago's BT laser sensor is a selectable 12bit HID data-reporting format. It also has a stand-alone base band processor with an integrated 2.4GHz transceiver. The built-in radio provides low-power and robust communications for applications operating in the 2.4GHz unlicensed ISM band. These features combined with Avago's BT 2.1 LaserStream sensor and 100 per cent synch capability will enable customers to design feature rich mouse solutions which extends long battery life.
