STiH273
HD cable/terrestrial STB processor with integrated demodulators
and low power standby controller
Data brief
Features
Description
■ ST40 applications CPU with 256 KB L2 cache
■ 16-bit LMI supporting DDR2/DDR3
The STiH273 uses the latest process technology
to provide a cost-effective, feature rich, highly
integrated SoC for set-top boxes (STBs). It is
targeted at the advanced decoding STB market
across cable and terrestrial networks, and is
suitable for operator markets (with advanced
security) and retail markets worldwide.
■ Decoding of H264, MPEG2, VC-1 and AVS HD
video streams
■ 3DTV decoding and display compatible with
HDMI 1.4a
■ Extensive connectivity (2 × USB 2.0 ports;
Ethernet MII/RMII/TMII port; SD/MMC card
port; eSATA port; PCI-e)
The STiH273 provides a solution for operators
and manufacturers to specify a range of cost-
effective, high performance STBs, including basic
zappers, interactive STBs, and DVR STBs with
content delivery possible using broadcast or
broadband networks or both (hybrid STBs).
■ Secure boot from SLC NAND Flash or Serial
NOR Flash; eMMC booting option
■ Low-power process and architecture
■ Integrated low power standby controller
■ High-quality video resizing and de-interlacing
■ Integrated Ethernet PHY
The STiH273 integrates a high performance dual
mode, cable/terrestrial receiver, supporting
DVB-C or DVB-T reception, channel
demodulation, and forward error correction (FEC).
The DVB-C receiver is compliant with ITU-T J.83
Annex A/C, and the DVB-T receiver is compliant
with ETSI EN-300744 v1.5.1, Nordig Unified
(v2.2.1) and DTG 7.2.
■ Targets two layer PCBs for cost-effective
zapper STB applications
■ Integrates dual mode DVB-T/DVB-C
