STB chipset meets DVB-S2 HDTV satellite standard requirements

Geneva—STMicroelectronics has launched a new set-top box front-end chipset for digital satellite high-definition TV equipment.

The STV6110A silicon tuner and the STV0903 single-channel satellite TV demodulator meet all the requirements of the DVB-S2 standard for broadcast applications.

The use of DVB-S2 by consumer equipment manufacturers is strongly increasing in a wide range of applications, including Pay-TV and free-to-air STBs, integrated digital TVs (iDTVs), PC TV cards and the emerging high-definition Blu-ray (BD) equipment.
The DVB-S2 standard increases the capacity of satellite communications links by 30% compared to DVB-S (Digital Video Broadcast for Satellite), which has been in use for many years by satellite operators worldwide.

Implemented in a cost-optimized process technology, the STV0903 demodulator operates seamlessly with ST's new STV6110A silicon tuner. It allows easy upgrade to ST's dual-channel STV0900 demodulator, which was launched in early 2007. The STV6110A silicon tuner is a replacement for ST's STB6000 and STB6100 tuners.

The STV6110A is also suitable for use in markets outside of the DVB-S2 standard, such as Japan, and China, in which new satellite standards are emerging. The STV6110A tuner and STV0903 demodulator combo provides manufacturers with a reduction in power consumption, offering 600mW and 1.2W, respectively, which is approximately 50% of the combined power consumption of ST's previous chipset.

Full software support is available via ST's application program interface (STAPI), enabling ease of use with ST's family of standard- and high-definition H.264/MPEG-4/VC-1 decoders. Both devices support QPSK and 8PSK modulation, as well as both DVB-S and DVB-S2 processing.

The STV0903 demodulator is packaged in a 14 x 14mm 128-pin LQFP and the STV6110A tuner, in a 5 x 5mm 32-pin QFN.

Pricing: In 10,000-unit quantities, the STV0903 demodulator is $9 and the STV6110A is $1.50.
Availability: Now in production volumes.
Datasheets: STV0903 and STV6110A.
