压控晶振(VCXO)是一种石英晶体振荡器，其振荡效率可以通过红外线加控制电压来改变或调制。它的振荡频率由晶体决定，频率可以通过控制电压在小范围内调节。VCXO多用于锁相技术和频率负反馈调制。通常，控制电压范围为0V至2V或0V至3V。VCXO的调谐范围为100ppm至200ppm。

VCXO压控晶振的技术规范中列有多项性能参数。这些参数往往是相互关联的。我们不能一味追求某些参数的高指标而忽视由此引起的其它参数的劣化。例如，VCXO压控晶振的允许的频率控制范围就是有限制的。一般来说，如果要求VCXO压控晶振的有较大的牵引度，则它在工作温度范围内的频率稳定度就较差。反之，如果对频率稳定度要求高，就很难得到较大的牵引度（>±200×10－6）。因此，正确了解压控晶振的技术规范和使用要求，对于在设计上用好这种器件是很关键的。
