Silicon Labs Unveils New Universal DVB Demodulators
Designed for digital terrestrial, satellite and cable reception applications
Silicon Labs has introduced a new family of universal demodulators that support the latest DVB standards for terrestrial, satellite and cable reception.
The Si216x/6x2 demodulator family
supports DVB-T, DVB-T2, DVB -T2-Lite, DVB-S, DVB-S2, DSS, DVB-C, DVB-C2 and ITU J.83 Annex A/B/C standards. The Silicon Labs announcement
noted, “New markets that are migrating to digital terrestrial TV broadcasting are switching directly from analog 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. Silicon Labs currently has the highest market share for DVB-T2 demodulators among all Tier 1 TV manufacturers. The field experience gained as a result of this leading market position is integrated into Silicon Labs’ latest generation of DVB-T2 demodulators.”
Regarding the importance of supporting the DVB-T2-Lite specification, Silicon Labs said, “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. Therefore, it is imperative that TV and STB makers use a demodulator that supports DVB-T2-Lite to address the global terrestrial broadcast market.
The Si216x/2x6 family is designed to reduce demodulator lock times for both DVB-C2 (cable) and DVB-T2. Silicon Labs claimed its devices “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 analog broadcasting coexist.” Faster lock times reduce the time required for channel changes.

Samples and production quantities of the demodulators are now available.
