OCXO oscillator ROM1490PA

electronicVCOclock

The ROM1490PA utilises market‐leading proprietary Mercury+™ technology delivering the world’s first ASIC‐based OCXO for Radio applications. This product family achieves ±20 ppb frequency stability over ‐40 to 95°C, with short term ageing less than 1 ppb/day and frequency slope as low as 0.1 ppb/°C. Extended operating temperature options are available on request. Using Rakon’s innovative high‐Q quartz crystals, ROM1490PA 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 ROM1490PA consumes only 0.4W at room temperature and has faster warm up times than traditional OCXOs.
