CXD2956AGL-1
GPS Baseband LSI
Description
The CXD2956AGL-1 is a dedicated LSI for the GPS
(Global Positioning System), satellite-based location
measurement system.
Compared with conventional methods, position
detection time and sensitivity are substantially
improved with the use of an advanced signal
processing scheme.
Although package sizes differ, the CXD2956AGL-1
has realized compatibility with a foot pattern to the
CXD2963GH.
This LSI used together with the Sony GPS RF down
converter IC enables the configuration of a 2-chip
system capable of measuring its position anywhere
on the globe. The CXD2956AGL-1 is ideal for use in
automotive, cellular handset, handheld navigation,
mobile computing and other location-based applications.
