Product Overview

The Epsilon Board Model EBO2 provides a fully integrated GPS synchronization solution with very accurate and stable time and frequency signals. Its high performance suits applications where excellent accuracy is required especially for synchronization of telecom wireline infrastructure, mobile wireless base stations, and 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 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.

Set-up and control of the EBO2 is via a serial interface. Status and alarms are via a TTL interface. Selection of all settings including antenna cable delay and choice of time scale (UTC or GPS) are user programmable. An Epsilon Board Evaluation Kit is available to facilitate development work.
