Sirius overlay decoder

Data Brief

Features

■ De-multiplexes the incoming overlay data

stream from the G3 Baseband processor

■ Maximal Ratio Combines the signals from the

three streams of data (TDM1, TDM2, COFDM)

■ Performs diversity combining two demodulated

soft symbol streams

TFBGA249

■ Utilizes internal TDM demodulators for

diversity combining cost sensitive applications

■ Performs error correction on the overlay data

■ Controls the Baseband Processor and DSP via

UART ports

■ Closes the processing loop to control the

Diversity Combiner or accepts second L2 input

for internal combining

– Required so theApplication Processor can

interface to a single client

■ Presents data to external application

■ Provides commands to the Application

processors

Processor

■ Channels I2S data from Baseband to

■ Memory Interfaces

Application Processors

– Data can be uncompressed audio

– Data can be "Data"

– SDR SDRAM to support the four second

buffer and de-interleaving

– FLASH for the storage of Firmware

■ Receives SSPv2 Commands

– UART

Description

– Parse data for Overlay and Legacy tune

commands

– Navigation

The STA264 ASIC is a fully integrated processor

for Sirius Satellite Digital Radio Service (SDARS)

that allows for decoding of Layer 2 hierarchical

data.
