The ROM7050PA utilises Rakon’s market-leading proprietary Mercury+™ technology, delivering the world’s smallest and lowest power OCXO for radio and small cell applications. This product family achieves excellent frequency stability of ±20 ppb over -40 to 95°C, with long term ageing less than 3 ppm in 10 years and frequency sensitivity to temperature (i.e. slope) as low as 0.1 ppb/°C. Low g-sensitivity and extended operating temperature options are available on request. Using Rakon’s innovative high-Q quartz crystals, ROM7050PA 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 (TCO) of customer equipment through improved reliability. With a miniature footprint, the ROM7050PA consumes only 400 mW at room temperature and has a faster warm up time than traditional OCXOs.
