The 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). Using a 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 adding features such as personal video recorder (PVR) and picture-in-picture, multiple demodulators are essential components.
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 new services such as video-on-demand (VOD) and high-definition television (HDTV). Silabs notes that the rapidly emerging DVB-C2 standard is increasingly important in the German TV market and is also becoming a “must-have” feature for the broader European market. High-end TVs designed for European consumers have begun supporting DVB-C2, and this trend will continue to accelerate. Many of Western Europe’s leading cable operators, representing more than 22 million households, have chosen to adopt the new DVB-C2 standard.
The Si216x/6x2 family supports the latest DVB-T2 specification (ETSI EN 302 755-V1.3.1), also known as DVB-T2-Lite. New markets that are migrating to digital terrestrial TV broadcasting are switching directly from analogue to DVB-T2-Lite. DVB-T2 adoption continues to expand to various African countries, as well as Singapore, Russia, India, Malaysia and Colombia. To date, 35 countries have adopted DVB-T2, 19 have deployed and nine are running trials.
The DVB-T2-Lite specification allows simpler receiver implementations for mobile and handheld reception. Additionally, the specification enables “scrambling of L1 post-signaling,” an attractive feature for new DVB-T2 infrastructure deployments that reduces the cost of the power amplifier in the broadcast transmitter. Emerging countries recently deploying DVB-T2 have implemented these lower cost transmitters. Legacy DVB-T2 demodulators that do not support DVB-T2-Lite will not be able to receive T2-Lite broadcasts.
