Introduction

The STi5189 uses state of the art process technology to provide an ultra low cost, full

featured, SD set-top box SOC. It is a highly integrated solution combining QPSK

(Quadrature Phase Shift Keying) demodulation, audio/video decoding and applications

processing into a single chip, suitable for MPEG2 based satellite networks worldwide.

The STi5189 provides a solution for operators to specify a range of low cost SD STBs

including low cost Zappers, Interactive STBs and DVR-capable STBs, with content delivery

using broadcast or broadband networks, or both (Hybrid STBs).

The STi5189 is optimized for secure Pay-TV applications with integrated DVB, DES, Multi2

and ICAM descramblers and smartcard interfaces. It also has advanced security features

normally found in mid-to-high end devices to further safeguard operator and content

investment.

The STi5189 offers enhancements in performance, features and integration to current users

of ST’s MPEG2 SD family of audio/video decoders and QPSK demodulators, whilst

reducing cost and time-to-market for the next generation of deployments. Few external

components are required to realize a complete STB solution, resulting in very low BOM

cost.
