Broadcom Introduces GPS Chip For Mobile Apps

Claiming to set new standards for performance and power consumption, the BCM4750 embarks as the company's first single-chip GPS receiver. Based on a 90-nm CMOS process, the device employs a Global Locate architecture, and can measure faint GPS signals both indoors and in urban canyon environments at signals as low as -162 dBm. It consumes less than 15 mW while navigating with one-second map updates. The BCM4750 also integrates a number of external components, resulting in a small footprint consuming less than 35 mm x 35 mm of board space including all necessary components for a typical cell-phone design. The chip comes with software that includes message-handling protocols and native support for LTO extended ephemeris service. BROADCOM CORP., Irvine, CA. (949) 926-5000.
