The fundamental unit of the high-reliability frequency source is low phase noise reference source, and the sources with optimum frequency stability of reference sources are high reliable crystal oscillator and atomic clock . even the atomic clock itself needs high reliable crystal oscillator 而高稳定的频率源又是以低相噪参考源为基础的,在各种参考源中频率稳定度最好的是高稳定晶体振荡器和原子钟,而原子钟本身也要用到高稳定晶体振荡器。
