Mercury™ and Mercury+™ Small Form Factor IC OCXO

Our small footprint OCXOs are based on our leading proprietary Mercury™ and Mercury+™ technology. They deliver excellent frequency stability over temperature. The ROM1490E as an example achieves ±5 ppb frequency stability over ‐40°C to +85°C combined with aging of less than 1 ppb/day. This highly integrated, ASIC based OCXO design has a minimal number of interconnections resulting in significantly enhanced reliability and therefore lowering Total Cost of Ownership (TCO) of the equipment. 

Applications: base stations, enterprise networking, small cells, network timing, Stratum 3E synchronisation (IEEE1588, SyncE), 5G RRHs, optical networks and microwave transmission systems.

Country of origin: New Zealand
