Description

interface (LMI)

The STi5251 is a new, cost-effective SD

advanced decoding STB SoC. The STi5251 is

ideally suited to cable, terrestrial and terrestrial/IP

hybrid networks. The STi5251 integrates in a

single IC a versatile DVB-C/DVB-T

■ Embedded DVB-C or DVB-T demodulator

■ Multi-stream, DVR capable, transport stream

processing

■ Flexible ST231-based audio decoder

demodulator/FEC (user mode selectable), multi-

stream transport demux, an ST40 applications

CPU, A/V decode, video processing, graphics and

display, advanced security, STB peripherals,

audio/video DACs, digital A/V outputs, USB 2.0

host controller with PHY and ULPI, SDIO SD-

MMC controller and Ethernet GMAC controller

with /MII/RMII/TMII interface.

■ Flexible ST231-based advanced video

decoder

■ Multi-channel flexible DMA controller

■ Extensive connectivity (dual USB controller,

Ethernet MAC/MII/RMII/TMII and SD-

MMC/SDIO)

■ Advanced security and DRM support including
