Intel has unveiled its first digital TV dual-channel demodulators housed on a single piece of silicon for the consumer electronics (CE) market segment. The new Intel CE 6250 dual-channel COFDM demodulator and CE 6251 dual-channel diversity-enabled COFDM demodulator expand Intel's CE offerings by allowing manufacturers, such as UK CE manufacturer TVonics, to deliver highly integrated advanced digital home entertainment capabilities for a variety of future consumer entertainment devices, such as personal video recorder set-top boxes (PVR STBs), integrated digital TV (iDTV) and TV-enabled personal computers (PC-TV).
Shipping in excess of 11 million DVB-T demodulator chips in 2006, Intel is building on the performance and power advantages established by its single channel devices.
To meet the needs of the DTV platforms in the European region, the Intel CE 6250 and CE 6251 are fully NorDig Unified 1.0.2 standard compliant.
By operating as two individual channels in a PVR, the Intel CE 6250 demodulator is specifically designed to give consumers the flexibility to watch one program while recording another, including a real-time broadcast picture-in-picture feature in iDTVs instead of a broadcast recording. For PC-TV cards, PCI Express and Mini-TV cards, it allows consumers to watch and record, download and edit TV programs.
The new demodulators use less than 280 mW (milliwatts) for a typical application.
Intel's new dual channel single chip demodulators are currently shipping. These devices are designed in 0.13 CMOS (complementary metal oxide silicon) technology and available in compact 80-pin LQFP (low-profile quad flat pack) measuring just 10 x 10 mm. Intel supports the products with a comprehensive evaluation system that includes a TNIM reference design, evaluation software and PC interface. Source code software device drivers are also available.
