DESCRIPTION

The STA450A is designed for digital radio receivers

compatible with the XMRadio SDARS System and in-

tegrates all the functions needed to perform the Ser-

vice Layer and Source Decoding:

– Bitstream Synchronization

– Service Layer (SL) Demultiplexing

– Auxiliary Data Management

– Conditional Access (CA) Control

– Service Components Extraction

– Service Components Decryption

– Audio and Voice Decoding

The extracted Audio and Data are made available

through different interfaces:

– I2S Audio Output

– S/PDIF Output

– Data Output Port

TQFP80
