STiH273

HD cable/terrestrial STB processor with integrated demodulators

and low power standby controller

Data brief

Features

Description

■ ST40 applications CPU with 256 KB L2 cache

■ 16-bit LMI supporting DDR2/DDR3

The STiH273 uses the latest process technology

to provide a cost-effective, feature rich, highly

integrated SoC for set-top boxes (STBs). It is

targeted at the advanced decoding STB market

across cable and terrestrial networks, and is

suitable for operator markets (with advanced

security) and retail markets worldwide.

■ Decoding of H264, MPEG2, VC-1 and AVS HD

video streams

■ 3DTV decoding and display compatible with

HDMI 1.4a

■ Extensive connectivity (2 × USB 2.0 ports;

Ethernet MII/RMII/TMII port; SD/MMC card

port; eSATA port; PCI-e)

The STiH273 provides a solution for operators

and manufacturers to specify a range of cost-

effective, high performance STBs, including basic

zappers, interactive STBs, and DVR STBs with

content delivery possible using broadcast or

broadband networks or both (hybrid STBs).

■ Secure boot from SLC NAND Flash or Serial

NOR Flash; eMMC booting option

■ Low-power process and architecture

■ Integrated low power standby controller

■ High-quality video resizing and de-interlacing

■ Integrated Ethernet PHY

The STiH273 integrates a high performance dual

mode, cable/terrestrial receiver, supporting

DVB-C or DVB-T reception, channel

demodulation, and forward error correction (FEC).

The DVB-C receiver is compliant with ITU-T J.83

Annex A/C, and the DVB-T receiver is compliant

with ETSI EN-300744 v1.5.1, Nordig Unified

(v2.2.1) and DTG 7.2.

■ Targets two layer PCBs for cost-effective

zapper STB applications

■ Integrates dual mode DVB-T/DVB-C

demodulation and FEC
