Single Chip GPS LSI

Description

176 pin LFLGA (Plastic)

The CXD2951GA-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 CXD2951GA-4 is ideal for use in automotive,

cellular handset, handheld navigation, mobile

computing and other location-based applications.
