DESCRIPTION

The SDARS is a satellite transmission system based

on two geostationary satellites on the East and West

coasts of the Continental United States (CONUS). In

the urban areas, where the line of sight reception of

the satellites is difficult or not possible, the service is

covered by terrestrial repeaters adopting a MultiCar-

rier Modulation scheme.

Designed for digital radio receivers compatible with

the XMRadio SDARS System, the STA400A Chan-

nel Decoder integrates all the functions to demodu-

TQFP144

ORDERING NUMBER: STA400A
