The ROM1490EA uses Rakon’s market‐leading proprietary Mercury+™ technology, delivering the world’s first ASIC‐based Stratum 3E OCXO.
This product family delivers ±10 ppb frequency stability over ‐40 to 95°C and ageing of less than 1 ppb/day; fully compliant with Stratum 3E specifications. The ROM1490EA is an ideal solution for Telecom Boundary Clocks (T‐BC) Class C and Class D, which require low dynamic noise contribution from oscillators over the operating temperature range. Holdover of a few hours is available for select temperature profiles.
Mercury+™ ASIC‐OCXOs enable lower Total Cost of Ownership of customer equipment through significantly enhanced reliability. With a small form factor and few discrete components, the ROM1490EA consumes only 0.4W at room temperature and has faster warm up times than traditional OCXOs.
