GNSS Ultra-low power RF Receiver IP

Description

This GNSS RF Receiver IP is silicon-proven in 22nm ULP process node, offers comprehensive support for all current satellite-based navigation systems, encompassing GPS (US), Galileo (EU), GLONASS (Russia), Beidou (China), QZSS (Japan), and SBAS. Tailored for battery-powered IoT and M2M applications, it concurrently accommodates L1/L2 and L5 frequencies.

Integrated within this IP are both integer-N (default) and dual-mode fractional-N frequency synthesizers, facilitating the utilization of a singular reference frequency across multiple modes. Its fully integrated Frequency Synthesizer (SX) features a wide-ranging VCO tuning capability, ensuring coverage across various frequency requirements and process corners. Moreover, it supports both single-system and multi-system operations.

This can be ported to any technology node subject to the availability of the RF front end. It can be supplied with the most stable firmware for accurate highly reliable location tracking along with support and upgrades.

This GNSS RF Receiver IP boasts high-level programmability, allowing optimization of power consumption and functionality across diverse scenarios. It is particularly well-suited for IoT and mobile tracking applications, thanks to its ultra-low power design. Furthermore, the RF IP incorporates an integrated reference clock buffer to ensure a stable reference frequency, thereby enhancing overall performance.
