Introduction STi5289

1 Introduction

The STi5289 is targeted at the latest operator and CE manufacturer requirements for
satellite STBs that use advanced decoding (H264/VC-1/MPEG2), and which conform to
DVB, CEA and ITU specifications.

The STi5289 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
possible using satellite broadcast or broadband networks, or both (Hybrid STBs).

The STi5289 is optimized for secure Pay-TV applications with integrated DVB, DES, AES,
Multi-2 and ICAM descramblers and smartcard interfaces.

The STi5289 offers enhancements in performance, features and integration to current users
of ST’s SD AVC family of audio/video decoders, while reducing cost and time-to-market for
the next generation deployments.

Features Benefits

Combines a DVB-S demodulator with STB
decoding and display functions

Serial Flash based secure boot and code
storage, integrated voltage regulator,
23 mm x 23 mm PBGA package

ST40 applications CPU,
32K I cache, 32K D cache

STMicroelectronics’ video decoding system with
ST231 processor

Dual USB 2.0 hosts, Ethernet MAC with
MII/RMII and TMII, PCI, SD-MMC/SDIO

Low-power process, design and architecture Best-in-class, low-power standby mode, to meet

Advanced 2D graphics and display subsystem
and 480p/576p display output

This highly integrated SoC helps to reduce board
area and manufacturing cost, allowing low-cost
and small-size STBs to be designed for DVB-S
networks

Enables further BOM optimization and cost
reduction of advanced decoding SD STBs

Superscalar performance from a single CPU core,
using standard tools and operating systems (Linux,
OS21)

Decoding of advanced standard definition MPEG2,
H264 and VC-1/WMV9 streams, with the
performance and flexibility for web-based content
decoding such as Flash, DivX, MJPEG and Real

Extensive high speed connectivity for the widest
range of STB peripherals, such as Flash drives,
external HDDs, home network controllers (for
example MoCA, Wi-Fi), memory cards

emerging energy standards for STBs. Dynamic
configuration of power to individual sub-systems
enables power-efficient active standby modes

Allows visually appealing user interfaces and video
rich navigation to be offered to consumers, while
high quality progressive output can be watched on
the latest displays
