GPS Baseband LSI

CXD2956AGL-1

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.
