MIPS Technologies Inc.'s silicon-proven GPS RF tuner IP integrates low-noise RF front-end for GPS receivers in the L1 band, enabling embedded system designers to decrease costs and time-to-market for next-generation GPS devices.

The GPS tuner IP is aimed at companies developing GPS devices, adding GPS functionality to other types of devices, or looking to reduce the form factor and development costs of a next-generation device. The IP is targeted at virtually any location application, such as high-end navigation systems in cars, cellphones and PDAs. Its cost and area advantages make it especially well suited for ultramobile devices, handheld games, portable media players, mobile PCs and digital cameras.

With standard digital output, the generation of MIPS Technologies' GPS Tuner IP core CI10084tg supports Global Navigation Satellite System (GNSS) systems in the L1 band and is also compatible with Galileo, for a broad range of markets and applications. The GPS Tuner IP core uses a fractional PLL, allowing designers to leverage the crystal frequencies available in the host application.

A wide range of flexible options lets system designers optimize parameters like power modes and baseband filter settings for their specific application. Automatic gain control and tuning provide autonomous operation independent of the selected baseband demodulator. The core has a die area of 4mm2 (including IO ring with ESD protections), with an integrated LNA and PLL loop filter to help maintain a small form factor.

MIPS Technologies' GPS IP solution is optimized for System-in-Package (SiP) integration, with a product roadmap targeting migration to 65nm to support future generations of satellite receivers within SoCs.
