Single chip processor/interface enables certified cable set-top boxes
At its introduction in January 2009, the STi7141 was the first device on the market to support HDTV, broadband Internet up to 100 Mbit/s thanks to its integrated cable modem, and sophisticated digital video recording functions in a single component. Leveraging the architectural advantages of the STi7141, the STiH225 features dual-core processing, which ensures full performance is always available for set-top box functions and for broadband communication.
The STiH225 is fully software compatible with the STi7141, allowing customers to migrate designs quickly and easily to the new device, taking advantage of DOCSIS 2.0 certification and support for Internet Protocol v6. A three-channel set-top box based on this device can be completed using very few additional components.
Designers are free to use three discrete cable tuners or a tuner module in the standardized network interface module form factor. This enables designers to reduce the printed circuit board area and bill-of-materials costs to deliver competitively priced, compact interactive set-top boxes that provide access to high-value services.
The STiH225 features:
- Linux, and OS21 compatible
- Multi-standard MPEG4/H.264/VC1, MPEG-2, SMPTE video decoding
- Multi-standard MPEG2/3/4, Dolby Digital (AC-3), Dolby Digital Plus audio processing
- Four USB ports
- eSATA interface to external HDD
- S-video/YPbPr/HDMI video output
- Three channels downstream channel bonding up to 100 Mbps
The STiH225 is sampling to lead customers, with volume production scheduled for January 2012.
