OCXO oscillator ROM1490PS

electronicVCOclock

The ROM1490PS uses Rakon’s market‐leading proprietary Mercury+™ technology, delivering the world’s first ASIC‐based and smallest OCXO in a hermetic package. This product family delivers ±10 ppb frequency stability over ‐40 to 85°C with short term ageing less than 1 ppb/day and frequency slope as low as 0.1 ppb/°C. Using Rakon’s innovative high‐Q quartz crystals, ROM1490PS offers superior close‐in phase noise performance, enabling Remote Radio Head PLLs to use a single reference clock to meet both network synchronisation requirements and air interface requirements. Mercury+™ ASIC‐OCXOs enable lower Total Cost of Ownership of customer equipment through improved reliability. With a small form factor and few discrete components, a ROM1490PS consumes only 0.4W at room temperature and has faster warm up times than traditional OCXOs.
