GPS time / frequency synchronisation generator
10 MHz | EC1S Spectracom

The Epsilon Clock™ 1S provides a compact synchronization solution with very accurate and stable time and frequency signals. The high performance suits a comprehensive range of applications where excellent accuracy is required especially for synchronization of telecom wireline infrastructure, mobile wireless base stations, emitters of digital audio or video broadcast.

An ovenized oscillator (OCXO) slaved to the GPS input source offers outstanding accuracy and phase noise. An optional Double Oven OCXO is available for a very low aging. The oscillator in conjunction with the EpsilTime™ smart predictive slaving algorithm mitigates the effects of inherent GPS noise and complies to the most stringent holdover mode requirements, such as CDMA-3G, if GPS is lost. Furthermore, the 10 MHz frequency reference is cycle locked to the 1 PPS, meaning that there are always exactly ten million cycles between 1 PPS occurrences. This unique feature is essential to avoid phase jumps and wander between time and frequency references.
