CXD2951GL-4

www.DataSheet4U.com Single Chip GPS LSI CXD2951GL-4 Description The CXD2951GL-4 is a dedicated single chip LSI for the GPS (Global Positioning System), satellite-based location measurement system. This LSI enables the configuration of a single chip system providing a costeffective, low-power solution. Compared with conventional methods, position detection time and sensitivity are substantially improved with the use of an advanced signal processing scheme. With the integration of both the Radio and baseband blocks into a single CMOS IC, the CXD2951GL-4 is ideal for use in automotive, cellular handset, handheld navigation, mobile computing and other location-based applications.
