1.为系统提供基本的时钟信号。通常一个系统共用一个石英晶振，便于各部分保持同步，有些通讯系统的基频和射频使用不同的晶振，而通过电子调整频率的方法保持同步。

2.晶振与锁相环电路配合使用，以提供系统所需的时钟频率。如果不同子系统需要不同频率的时钟信号，可以用与同一个晶振相连的不同锁相环来提供。

3225mm小体积的无铅SMD晶振编码Q22FA23V0048216，晶振是晶体振荡器的简称，在电气上它可以等效成一个电容和一个电阻并联再串联一个电容的二端网络。电工学上这个网络有两个谐振点，以频率的高低分其中较低的频率是串联谐振，较高的频率是并联谐振。由于石英晶体自身的特性致使这两个频率的距离相当的接近，在这个极窄的频率范围内，晶振等效为一个电感，所以只要晶振的两端并联上合适的电容它就会组成并联谐振电路。这个并联谐振电路加到一个负反馈电路中就可以构成正弦波振荡电路，由于晶振等效为电感的频率范围很窄，所以即使其他元件的参数变化很大，这个振荡器的频率也不会有很大的变化。
