Broadcom will be showcasing a new chip at the Institute of Navigation conference in Ft. Worth, Texas today. The BCM4750 chip is aimed to have low power consumption and high sensitivity, as well as some new advancements which would allow for signals to reach indoors and into urban canyons. We often forget that Broadcom actually does some, y’know, engineering amidst all the litigation.
“The Broadcom BCM4750 is produced in a low cost 90 nanometer CMOS process and features superior receiver technology and tracking sensitivity. The receiver makes full use of the Global Locate architecture, and can measure the faintest GPS signals deep indoors and in “urban canyon” environments at signal levels as low as -162 dBm. It also consumes less than 15 mW while navigating with one second map updates, less than half the power of competitive solutions according to published datasheets.”
