STA240

Sirius SDARS channel, service & source decoder

Features

■ 2 Satellite and 1 terrestrial signal demodulators

and decoders

■ Advanced DSP processor to implement PAC

audio decoder

■ Requires a single 17MHz clock reference; all

high-speed clock signals are derived using

on-chip PLL

■ Programmable I2S to support 32K/48K/44.1K

audio sample rate (32K/48K Sample rates use

internal clocks, 44.1K Sample rate uses

external clock)

■ I2C master interface to control tuner and audio

DAC

■ External control through uart interface using

sirius standard protocol (SSP) over RS-232

Analog to digital converters

■ Three internal 10 BIT A/D converters for

76.5MHZ if signals conversion

Low power technology

■ 1.2V, 0.13 µm technology

■ 3.3V capable I/OS

Description

STA240 is a fully integrated 3rd generation

Baseband signal processor for Sirius Satellite

Digital Radio Service (SDARS). It is implemented

using ST Micro's advanced 0.13µm HCMOS9

technology.

It allows a highly efficient implementation of a

Sirius “SDARS Satellite Digital Audio Radio

Service” receiver when used with its companion

STA210 tuner ASIC.

STA240 is packaged in a low profile BGA (LBGA

19x19)
