Introduction

The STiH251 is designed to be optimized, both in cost and performance, with the most

advanced can tuners and silicon tuners available on the market and is compliant with

DVB-T2 and DVB-T standards.The STiH251 front end has one of the lowest power

consumptions on the market today. This has been made possible thanks to technology and

clock rate management. This also has the advantage of improving channel acquisition and

re-acquisition efficiency.

The STiH251 is delivered with a full suite of low-level drivers and application software, with

detailed user manuals and reference design schematics to enable seamless integration in

complex digital TV systems such as iDTV, set-top boxes or PCTV dongles.

Features

Benefits

Combines a configurable DVB-T2 and DVB-T

demodulator with STB decoding and display

functions

This highly integrated SoC helps to reduce board

area and manufacturing cost, allowing low cost and

small size STBs to be designed for DVB-T2 and

DVB-T networks

Applications CPU,

32K I cache, 32K D cache

Superscalar performance from a single CPU core,

using standard tools and operating systems (Linux,

OS21)

STMicroelectronics’ video decoding system with

ST231 processor

Decoding of advanced high definition standards for

MPEG2, H264, VC-1 broadcast, with the

performance and flexibility for web-based content

decoding such as Flash

Real

®

Dual USB 2.0 hosts, e-SATA,

Ethernet MAC with MII/RMII and TMII,

PCI

Extensive high speed connectivity for the widest

range of STB peripherals, such as Flash drives,

external HDDs, home network controllers (for

example MoCA

on

Low power process, design and architecture

Best in class, low power standby mode, to meet

emerging energy standards for STBs. Dynamic

configuration of power to individual sub-systems

enables power-efficient active standby modes

Advanced 2D graphics and display subsystem

which also supports 3D user interface effects

and 1080p60 display output

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 high definition displays
