STMICROELECTRONICS STI5517

STi5517
Low-cost set-top box decoder
DATA BRIEF
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 antiflicker filtering) as an alternative image format for
the OSD plane. With an integrated highperformance 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.
