ADNS-7630:BT SoC LaserStream™ Sensor

ADNS-7630 is the world’s first one-chip Bluetooth (BT) 2.1 System-on-Chip (SoC) LaserStream navigation sensor chip for laser-illuminated navigation system Driven by Avago’s LaserStream navigation technology and proprietary optimized cum efficient RF transceiver architecture, it provides a fully integrated and feature-rich navigation system for wireless mouse applications and other integrated input devices. This compact, laser navigation sensor engine from Avago, integrates a BT transceiver, stand-alone baseband processor and VCSEL illumination into a single chip package to provide a complete SoC solution that provides fast and secure connectivity, and easy integration into mouse designs.

ADNS-7630 complies with Bluetooth specification version 2.1 and HID profile version 1.0. The built-in radio provides low-power, low-cost and robust communications for  applications operating in the 2.4-GHz unlicensed ISM band.

Additionally, this new laser sensor has several features that can be configured via an external EEPROM to simplify mouse and provide flexibility for product customization.

This chip is available in 58-pin custom designed QFN package and designed to be used with the ADNS-7100-001 laser mouse lens to achieve the optimum performance featured in this document. These parts provide a complete and compact navigation system with no moving parts and precise optical alignment to facilitate high volume assembly. Avago has pre-calibrated the laser power prior shipment to meet IEC/EN 60825-1 Class 1 Eye Safety Standard, thus no laser power calibration is required at manufacturer site, therefore reducing assembly time and associated cost.
