Using PLL synthesis technology such as frequency multiplication and frequency division, may obtain the multi-frequencies, the high stableoscillator signal output.
利用锁相环的倍频、分频等频率合成技术，可以获得多频率、高稳定的振荡信号输出。

To use a crystal unit as an oscillator, its oscillated frequency is required to be stable against temperature variations.
石英晶体作为谐振器在使用时，要求其谐振频率在温度发生变化时保持稳定。
