在有源晶振中我们知道包含有普通石英晶体振荡器（OSC晶振），温补晶振（TCXO晶振），压控晶振（VCXO晶振），压控温补晶振（VC-TCXO晶振），恒温晶振（OCXO晶振），32.768K有源晶振，差分晶振等，其中最常用的还是普通石英晶体振荡器、温度补偿晶振和压电控制晶振。我们都知道石英晶振的频率精准度直接影响晶振性能，而温度作为最大外在因素也被我们研究来研究去，最后我们终于都把TCXO晶振懂了个透彻，但对VCXO晶振我们了解的实际上是少之又少。

在石英晶振中谐振器和振荡器的区分相信大家都非常了解了。石英晶体谐振器成为不带电压的石英晶振或是无源晶振，而石英晶体振荡器则称为带电压的石英晶振也就是有源晶振，并且和谐振器相比振荡器还根据有源晶振的性能不同分为：普通石英晶体振荡器即普通有源晶振OSC，温度补偿晶振TCXO晶振,压控晶体振荡器VCXO，压控温补晶振VC-TCXO晶振，差分晶振LV-PECL晶振，恒温晶体振荡器OCXO晶振，还有就是刚加入有源晶振系列还不久的32.768K有源晶振。
