White Papers: Cost-effective Synchronization for Digital Broadcast In Europe, Middle East, Africa and Southeast Asia, broadcasters are looking to the DVB-T2 standard to upgrade from analog transmission, their current DVB-T implementation, or as a supplemental network. Similarly, in South America, ISDB-T is being implemented. These and other standards rely more and more on single frequency networks (SFN) to efficiently utilize wireless frequency spectrum. SFNs require synchronization so for each instant of time, every transmission station is broadcasting the same digital data at the same exact frequency. pdf - 739 KB

Technical Notes and Briefs: EpsilTime™ Synchronization Algorithm Spectracom time and frequency synchronization management algorithms, like EpsilTime™ used in models EC20S and EC22S, uses smart predictive technology to mitigate the effects of inherent GPS and oscillator noise, improves accuracy if GPS is lost(holdover), and corrects drift in the 10 MHz and 1PPS outputs simultaneously. That means there are always 10 million frequency cycles between every one pulse-per-second. pdf - 122 KB
