Description
The STiH223 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 American and Asian cable networks that
utilize the ITU-T J.83 annex B physical layer. It is
suitable both for operator (with advanced security)
and retail markets.
The STiH223 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 STiH223 integrates a high performance cable
receiver, supporting reception, channel
demodulation, and forward error correction (FEC)
and is fully compliant with the ITU-T J.83 annex B
standard.

Introduction STiH223
1 Introduction
The STiH223 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
STiH223 keeps pace with the latest advanced security requirements of the main CA
vendors, and an integrated standby controller enables the STiH223 to target stringent low
power regulations.
