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, DVB-H, DVB-SH, T-DMB, FLO, DAB or DRM) in SFN modes, as well as wireless synchronization of BTS (WiMAX, CDMA, TD-SCDMA).

An ovenized oscillator (OCXO) slaved to the input source offers outstanding accuracy and reduces phase noise. The smart EpsilTime™ Kalman-based algorithm allows intelligent input signal filtering, providing adaptability to the quality of the active input reference (GPS, external PPS). If the input reference is disrupted, the oscillator maintains time (SFN) and frequency (MFN & SFN) accuracies in holdover mode.

The Epsilon Clock Model EC20S is also available with an optional Rubidium oscillator, which provides even greater holdover stability. Setup, status, and alarms are accessible through an Ethernet 10/100 Base-T interface, through embedded SNMP protocol, or through the Web User Interface. The antenna cable delay and the choice of time scale (UTC or GPS) are programmable.
