STi5517

Low-cost set-top box decoder

Rev. 1

DESCRIPTION

STMicroelectronics has developed two devices

for low cost cable, satellite and terrestrial STBs.

The STi5516 and STi5517 integrate more core

STB functions into a single device than ever

before,

offering

STB

manufacturers

the

opportunity

to

build

cost-effective

solutions

powered by devices from the leading supplier of

MPEG-2 ICs.

Used with ST’s established demodulator devices,

the STi5516 and STi5517 form a complete chipset

for low-cost STBs across all application areas.

The

STi5517

contains

additional

advanced

features: it supports RGB16 graphics (with anti-

flicker filtering) as an alternative image format for

the

OSD

plane.

With

an

integrated

high-

performance

DMA

engine,

it

is

ideal

for

applications requiring high-resolution graphics.

The STi5517 has built-in D1 and PCM input

interfaces to allow the IC to be used in applications

requiring legacy analog support.

A common programme guide can then be used for

both digital and analog services.

The STi5517 has enhanced security features to

help protect the integrity of set-top boxes against

piracy.
