一图看懂有源晶振和无源晶振的区别
晶振是在电路中提供频率基准的被动元器件，它能产生频率高度稳定的交流信号，使得电路工作在一个稳定的频率范围内，多数应用于汽车、数字、电子等行业。
晶振可分为有源晶振与无源晶振。一般我们说的“晶振”指的是有源晶振，而无源晶振通常叫“晶体”，或者叫“谐振器”。
两者的主要区别是：有源晶振自身即可起振，而无源晶振则需要外加专门的时钟电路才能起振。
总体来看，有源晶振的精度、稳定度等方面均要好于无源晶振，尤其是在精密测量领域，大部分用的都是高规格的有源晶振，以方便把各种补偿技术集成在一起，减少设计复杂性。
另外，由于自身增加了超振电路，有源晶振体积一般都会比无源晶振要大些，但现在很多有源晶振都是表贴的，体积得以缩小，与无源晶体差不多甚至更小些。体积变小使得有源晶振的应用更多，尤其是消费电子领域。

详解有源晶振与无源晶振的区别
晶振作为我们掌握电子设备同步节拍的关键，它的主要作用是产生稳定的频率信号。传统意义上，我们通常将晶振分为有源晶振和无源晶振，有源晶振和无源晶振各有优势和劣势，选择哪种类型的晶振取决于具体的应用需求。本文赛思详细介绍了有源晶振和无源晶振的区别。
