NaviLink™ 6.0 single-chip A-GPS/Bluetooth®/ULP/FM Rx/Tx solution: NL5500 - Availability Disclaimer

As the popularity of global positioning satellite (GPS) systems continues to grow, mobile handset users are demanding similar functionality on their mobile phones. In addition, the vast majority of mobile handsets include Bluetooth wireless technology to provide wireless connectivity between devices. A growing segment of the mobile handset market is incorporating FM radio receiver/transceivers (Rx/Tx) to allow users to enjoy FM radio when not making phone calls. Built on TI’s experience and expertise in multiple radio solutions, the NaviLink 6.0 (NL5500) is the industry’s first single chip that combines assisted global positioning satellite (A-GPS), Bluetooth 2.1 and ultra-low power technologies, as well as FM receive/transmit capabilities.

Built on TI’s DRP™ single-chip technology at 65 nanometer (nm), the highly integrated and cost-effective NaviLink 6.0 solution enables manufacturers to introduce sleek, affordable and high-performance handsets with GPS capabilities to the large mid-tier market and drive increased usage of popular GPS-based applications such as 3-D mapping, location-based services and safety services. NaviLink 6.0 maximizes board space by 40 percent, enabling the smallest possible phones and reduces power consumption by up to 50 percent over previous TI solutions. The mobile user experience is further enhanced by enabling consumers to enjoy simultaneous activities such as navigating, having a conversation using a Bluetooth headset, while also transmitting an MP3 file to the car radio using the FM transmit capability. Further improving the user experience, the NaviLink 6.0 solution includes enhanced algorithms to dramatically reduce the “time to first fix” (TTFF) over previous TI solutions. Integrated “position optimizer” software also includes support for navigation sensors, delivers superior accuracy in weak satellite signal areas, such as urban centers and heavily wooded areas.

The NaviLink 6.0 solution also addresses the complex coexistence challenge. TI’s hardware implementation and software algorithms are optimized to ensure seamless coexistence between GPS, Bluetooth, FM, WLAN and cellular functions.
