STi5197L

Cost-effective QAM demodulator and MPEG2 decoder

for SD set-top box applications

Features

■ ITU-T J83 Annexes A/B/C, DVB-C compliant

■ 256 QAM demodulation and FEC sub-system

■ MPEG2 MP@ML video decoding

■ Audio decoding (MPEG1, 2, MP3, Dolby

Digital 5.1)

■ Linux and OS21 compatible ST40 applications

CPU

■ 16-bit SDR/DDR1 compatible local memory

interface

■ Multi-stream, DVR capable, transport stream

processing

■ Extensive connectivity (USB 2.0 host/ULPI,

Ethernet MAC MII/RMII, DVB-CI)

■ Cable STBs can be produced with very small

BOM and two-layer PCBs

■ Active and passive low power modes

■ Integrated voltage regulator

Description

The STi5197 integrates in a single IC, QAM

demodulation, FEC, Multi-stream transport

demultiplexing, an applications CPU, audio/video

decode, video processing, graphics and display,

STB peripherals, audio/video DACs, digital

audio/video outputs, USB 2.0 host controller/ULPI

and an Ethernet MAC MII/RMII.

The STi5197L is a feature-optimized variant for

Asian markets.
