CG2900 - GPS_Bluetooth®_FM RX/TX


General Description

CG2900 - GPS, Bluetooth® AND FM RX/TX SINGLE CHIP

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.

Key Features

Bluetooth®

  • Bluetooth V4.0 (including BT Low Energy dual mode) + HS
  • Integrated PA (+13 dBm output power) and high sensitivity (-92 dBm) provides an improved audio quality and range for a better user experience
  • Embedded WBS and stereo SBC codec offload host and reduce system power consumption

FM

  • Integrated Rx/Tx antenna
  • Rx sensitivity of 1.1µV EMF
  • 8.2 mA Rx; 8.5mA Tx in active mode
  • RDS on chip; no host wake up to conserve power

GPS

  • -163 dBm acquisition sensitivity and -165 dBm tracking sensitivity with embedded LNA (single-ended antenna)
  • Autonomous (cold start) TTFF <38 s
  • A-GPS (hot start) TTFF <1 s
  • Low power tracking, 1fix/sec: 8.3 mA => 30 hours tracking with 850 mAh battery

System

  • Enhanced WLAN coexistence with ePTA technology
  • UART, PCM, I²S, SPI
  • 1.8 V single supply or direct battery connect

Package

  • Small WLCSP package for a PCB solution size below 35 mm²
