STA264
Sirius overlay decoder
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
■
Utilizes internal TDM demodulators for
diversity combining cost sensitive applications
■
Performs error correction on the overlay data
■
Closes the processing loop to control the
Diversity Combiner or accepts second L2 input
for internal combining
■
Presents data to external application
processors
■
Channels I2S data from Baseband to
Application Processors
– Data can be uncompressed audio
– Data can be "Data"
■
Receives SSPv2 Commands
– UART
– Parse data for Overlay and Legacy tune
commands
– Navigation
■
Controls the Baseband Processor and DSP via
UART ports
– Required so theApplication Processor can
interface to a single client
■
Provides commands to the Application
Processor
■
Memory Interfaces
– SDR SDRAM to support the four second
buffer and de-interleaving
– FLASH for the storage of Firmware
Description
The STA264 ASIC is a fully integrated processor
for Sirius Satellite Digital Radio Service (SDARS)
that allows for decoding of Layer 2 hierarchical
data.
