CG2900 - GPS, Bluetooth® AND FM
RX/TX SINGLE CHIP
Advanced radio resource management for state-of-the-art coexistence and extended battery life in connected mobile devices
Built in 45 nm CMOS, the CG2900 is a single-chip GPS, Bluetooth and FM Rx/Tx device. It is designed from the ground up to ensure seamless coexistence and high robustness against cellular interferers, ready for mobile platform integration. With the smallest footprint in the industry and an unprecedented level of integration, it is designed to enable small and thin devices. Low device power consumption, complemented by advanced host offloading features such as MP3, RDS, SBC, etc., further lower system energy usage for a much better user experience.
