Description
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.
The STiH273 provides a solution for operators
and manufacturers to specify a range of costeffective, high performance STBs, including basic
zappers, interactive STBs, and DVR STBs with
content delivery possible using broadcast or
broadband networks or both (hybrid STBs).
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.

Introduction STiH273
1 Introduction
The STiH273 offers current users of ST’s growing family of advanced decoding ICs
enhancements in performance and features, enabling operators to offer consumers new
multimedia-rich services and viewing experiences, including new 3DTV features. Faster
DDR3 memory is also supported, and the applications CPU benefits from an L2 cache. The
STiH273 keeps pace with the latest advanced security requirements of the main CA
vendors, and an integrated standby controller enables the STiH273 to target stringent low
power regulations.
Features Benefits
Integrated dual mode DVB-C/DVB-T
demodulation/FEC.
ST40 applications CPU, with 32KI and 32KD L1
caches and 256K L2 cache.
Integrated low power standby controller within its
own power island.
Latest generation of ST's Delta video decoder
coupled with a High Quality Video Display
Pipeline (HQVDP).
Dual USB 2.0 hosts, eSATA, Ethernet MAC with
MII/RMII/TMII interfaces, PCI-e, SD-MMC/SDIO
interface.
Highly integrated STB solution, reducing
component count and manufacturing BOM.
High performance processing for applications and
middleware.
Secure hibernation to, and fast resume from, very
low power passive standby mode, targeting STB
standby power < 0.5 W.
Decoding of advanced high definition standards
(MPEG2, H264, VC-1, AVS) plus the performance
and flexibility for web-based content decoding such
as Flash
impacting applications CPU performance.
Extensive high speed connectivity for the widest
range of STB peripherals, such as Flash drives,
external HDDs, Ethernet, home network controllers
(such as MoCA
memory cards.
®
, DivX™, MJPEG and Real®, without
