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 cost-
effective, 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.
