Description
The STi5251 is a new, cost-effective SD
advanced decoding STB SoC. The STi5251 is
ideally suited to cable, terrestrial and terrestrial/IP
hybrid networks. The STi5251 integrates in a
single IC a versatile DVB-C/DVB-T
demodulator/FEC (user mode selectable), multi-
stream transport demux, an ST40 applications
CPU, A/V decode, video processing, graphics and
display, advanced security, STB peripherals,
audio/video DACs, digital A/V outputs, USB 2.0
host controller with PHY and ULPI, SDIO SD-
MMC controller and Ethernet GMAC controller
with /MII/RMII/TMII interface.
