ECS伊西斯石英晶体和陶瓷谐振器
区别以及为什么晶体振荡器可能是更好的选择
石英晶体谐振器和陶瓷谐振器类似地激活和工作，因为当AC信号分别施加到它们时，它们都机械振动。区别在于石英晶体谐振器由石英晶体制成，而陶瓷谐振器由陶瓷元件制成。
什么是石英晶体？
石英晶体能够在所需的频率范围内“振荡”,只需很少的功率就能保持其激活状态。晶体可以指定精确的频率稳定性，随着周围热量的增加，晶体振荡器能够在-20 ~+70°c范围内以10 PPM(百万分之一或0.001%)的最小频率变化保持频率稳定性。这种紧密的稳定性使晶体适合ZigBee/蓝牙和其他无线应用。
从电视到有电子元件的儿童玩具，晶体振荡器随处可见。
什么是陶瓷谐振器？
贴片晶振陶瓷谐振器的工作原理类似于晶体。陶瓷谐振器利用电气元件内的频率，但与频率容差为10~30PPM的晶体不同，陶瓷谐振器的频率容差为0.5%或5.000PPM，通常用于绝对稳定性不重要的微处理器应用。
这里有一个简单的例子来说明这一点。百分比差异类似于奥林匹克竞赛。毫秒可能是金牌或银牌之间的差别。但是有了电子元件，差别就更大了。
此外，晶体采用密封封装，因此它们总是比环境密封的陶瓷谐振器更受推荐，因此晶体推荐用于宽温度范围或恶劣环境。
