Silicon Labs Demodulator Simplifies Video Front-Ends for TVs and Set-Top Boxes

by donpedro

Silicon Laboratories Inc. introduced the broadcast video industry’s most advanced, single-chip multimedia demodulator, enabling developers to simplify the design of iDTV, set-top box (STB) and Blu-ray/DVD recorder products. The new Si2169 device is the first demodulator to integrate the emerging DVB-T2 standard, advanced DVB-S2 standard, and existing DVB-T, DVB-S and DVB-C standards into a single CMOS chip supporting terrestrial, satellite and cable TV broadcast. The Si2169 is complemented by the Si2168, a pin-compatible DVB-T2/T/C demodulator designed for terrestrial and cable TV broadcast.
The Si2168/69 demodulators offer the industry’s highest level of DVB-T2 terrestrial broadcast performance, outperforming other competing DVB-T2 demodulators in challenging reception conditions and fully complying with the NorDig 2.2.1 and D-Book 7 specifications. Offering superior echo performance in all DVB-T2 transmission modes, the new demodulators enable the industry’s fastest DVB-T2 channel lock times under the most challenging echo conditions. In fact, Silicon Labs has implemented a special architecture to reduce DVB-T2 lock times to industry-leading values unlike competing demodulators that typically require significantly longer time to lock onto difficult channels.
