High End Telecom Discrete OCXO

A range of double oven and single oven OCXOs designed as a compact and smart frequency source and timekeeping reference for all synchronisation systems, including precision positioning system-based equipment. They provide superb frequency stability versus operational temperature (FvT) ranges. For instance, the ROX5252T1 model in this series achieves an FvT of ±0.1 ppb over a -20 to 70°C temperature range. 

Applications: Stratum 2 timing modules, time and frequency references, wireless and LTE-TDD base stations, IEEE 1588 (G.8263, G.8273.x), SyncE & Stratum 3E modules, time & frequency references, carrier networking, instrumentation, test equipment and broadcasting.
