SUMMARY OF BENEFITS Advanced low-power RFCMOS technology and low-power
tracking at 15 mW for the longest battery life
SINGLE-CHIP AGPS SOLUTION
FEATURES Single-chip solution (AGPS baseband and CMOS RF frontend integrated on a single-die) minimizing board space footprint (<35 sq mm2 PCB area for a complete AGPS solution)
Host communication via two-wire UART, I2C, or SPI with
baud rates as low as 9.6 Kbps
Up to 2-Hz update rate Real-time hardware correlator engine (fast acquisition and
high-sensitivity) capable of tracking 24 satellites simultaneously
High-sensitivity, -157 dBm assisted acquisition sensitivity
(with coarse time assistance) and -162 dBm tracking sensitivity, enabling indoor and deep urban operation
Broadcom software provides protocol layers for con
