EC20S Epsilon Clock

High-performance GPS/GLONASS Clock Designed to Exceed Digital TV, Digital Radio, 4G Base Stations, Satcom Time and Frequency Synchronization Requirements

The Epsilon Clock Model EC20S provides accurate and stable time and frequency signals for your high-performance synchronization application. The unit’s optimized architecture is well-suited to transmitter synchronization of digital broadcast signals (DVB-T/T2, T-DMB, DAB or DRM) in Single Frequency Networks (SFN) modes: the high port density allows to synchronize up to 10 emitters simultaneously on the same site.
