Silicon Labs has announced a family of universal digital video broadcast (DVB) demodulators that support the latest worldwide DVB standards for cable, terrestrial and satellite reception. Intended to simplify the design of complex, high-performance video front-ends for integrated digital TVs (iDTVs) and set-top boxes (STBs), the Si216x/6x2 family includes the industry's first dual-channel DVB demodulators targeting multi-receiver iDTV and STB applications, stated the company.

Silicon Labs' Si216x/6x2 demodulator family supports all first and second-generation DVB broadcast standards for cable (DVB-C2/C, ITU J.83 Annex A/B/C), terrestrial (DVB-T2/T) and satellite (DVB-S2/S, DSS). Leveraging Silicon Labs' industry-leading digital demodulation architecture, the single-channel Si216x and dual-channel Si216x2 demodulators enable excellent reception performance for each DVB standard while minimising front-end design complexity, footprint size, system cost and power dissipation. For TV and STB makers looking to add additional features such as personal video recorder (PVR) and picture-in-picture, multiple demodulators are essential components. Silicon Labs' dual demodulators enable TV/STB makers to simplify and reduce the cost of these multi-receiver designs.

The Si216x/6x2 family includes single and dual demodulators that comply with the recent DVB-C2 specification for cable reception, enabling highly efficient use of existing cable networks for delivery of innovative services such as video-on-demand (VOD) and HDTV. It also supports the latest DVB-T2 specification (ETSI EN 302 755-V1.3.1), also known as DVB-T2-Lite, which allows simpler receiver implementations for mobile and handheld reception.

Silicon Labs' Si216x/6x2 family is designed to reduce demodulator lock times across the DVB-C2/C/T2/T/S2/S standards. The demodulators demonstrate very short lock times in DVB-C2 mode, and they provide the industry's fastest DVB-T2 lock times, even in the presence of co-channel interference (CCI), which is an important consideration in countries where DVB-T2 and analogue broadcasting coexist, noted the firm. Fast lock time is a critical feature for TV and STB makers since it enables shorter "zapping" time (the speed of changing channels), an attractive consumer experience feature for TV viewers.

The single-channel Si216x demodulators use the same 7 x 7mm QFN-48 package as Silicon Labs' previous demodulator family, providing pin-to-pin compatibility, simplifying board design and reducing cost. The dual Si216x2 demodulators are pin-compatible in a compact 8 mm x 8 mm QFN-68 package. The Si216x and Si216x2 demodulators share the same API software, enabling customers to easily adapt their application software to the demodulators and upgrade their iDTV and STB products to the latest DVB-T2-Lite and DVB-C2 features.

Samples and production quantities of the Si216x and Si216x2 DVB demodulators are available. Depending on the supported DVB standards, product pricing in 10,000-unit quantities begins at $6.86 for single-channel demodulators.
