Introduction

The STiH225 is a highly integrated system-on-chip (SoC) designed to meet the demanding

need of the interactive cable set-top box market. The STiH225 integrates all the major

system functions into a single device, and provides world leading, multi-layer, advanced

security technologies to protect valuable video and audio assets.

Features

Benefits

Combines a cable transceiver and ITU-T J.83

A/B/C demodulator with STB decoding and

display functions

This highly integrated SoC helps to reduce board

area and manufacturing cost, allowing cost-

effective and small-size STBs to be designed for

ITU-J.83 A/B/C (DVB-C, SARFT, SCTE-40)

networks

Integrates EuroDOCSIS/DOCSIS 2.0 cable

modems with support for DOCSIS 3.0 down-

stream channel bonding

The embedded EuroDOCSIS and DOCSIS cable

modems are capable of providing DOCSIS set-top

gateway, interactive multimedia and internet

access for the digital cable market

Serial Flash-based secure boot and code

storage; 35 mm x 35 mm x 2.30 mm PBGA

package

Enables further BOM optimization and cost

reduction of advanced decoding SD STBs

ST40 applications CPU,

32 K I cache, 32 K D cache

Superscalar performance from a single CPU core,

using standard tools and operating systems (Linux)

STMicroelectronics' DELTA video decoding

system with ST231 processor

Decoding of advanced standard definition MPEG2,

H.264 and VC-1/WMV9 streams, with the

performance and flexibility for web-based content

decoding such as Flash, DivX, MJPEG, XviD and

Real

Dual USB 2.0 hosts, dual Ethernet MAC with

one PHY compatible with MII/RMII and GMII

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

Advanced 2D graphics and display subsystem

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
