日本EPSON爱普生无源晶振Q22FA2380032900与有源晶振内部结构

有源当我们的产品需要精度较高、接线尽可能简单的情况下就诞生了一种将起振电路IC集成到与水晶一起封装到外壳里的晶振,即有源晶振、振荡器,其精密度与稳定性高于无源晶振.

应用在实际的整改中,爱普生晶振关于时钟超标时钟是EMC工程师头疼的问题,绝大部分的时钟来源又是由晶振提供,用常规方法将周边配置电路重新匹配、隔离、滤波、屏蔽后依然无法解决这个难点.

无源当晶体通过基座、外壳、锌白铜、上盖等通过数十项工艺后就做出了我们的无源晶振.作为电子工程师都知道无源晶振需要起振还需要外围的起振电路,所以这种简单的晶振也叫晶体、无源晶振,优点主要为信号电平可变,低成本、低功耗等优势,应用场景十分丰富.

可以看出日本进口晶振无源晶振只需要两个引脚即可,即使做成4PIN的贴片晶振也只用到其中两个PIN脚,而有源晶振从原理上就决定了需要三个PIN脚才能工作,其中一个悬空的引脚有的厂家也有做使能端.
