CXD2951GA-1
Single Chip GPS LSI
Description
176 pin LFLGA (Plastic)
The CXD2951GA-1 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
RF and baseband blocks into a single CMOS IC, the
CXD2951GA-1 is ideal for use in automotive, cellular
handset, handheld navigation, mobile computing and
other location-based applications.
