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。晶振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？

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10~30 PPM的晶体不同，陶瓷谐振器的频率容差为0.5%或5，000 PPM，通常用于绝对稳定性不重要的微处理器应用。美国伊西斯石英晶体.

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。

The Differences And Why A Crystal Oscillator May Be A Superior Choice

Quartz crystal resonators and ceramic resonators activate and work similarly as they both vibrate mechanically when an AC signal is applied to each respectively.

The difference is that a quartz crystal resonator is made from a quartz crystal and a ceramic resonator is from ceramic components.

What is a Quartz Crystal?

Quartz Crystals are able to “oscillate” within the desired frequency with little power required to keep it activated. Crystals can be specified with a precise frequency stability and as the surrounding heat increases, the crystal oscillator is able to keep the frequency stability with minimal frequency change with a 10 PPM (parts Per Million or 0.001%) over -20 ~ +70°C. The tight stability makes crystal suitable for ZigBee/Bluetooth and other wireless applications.

Crystal oscillators can be found in everything from televisions to children’s toys that have electrical components.

What is a Ceramic Resonator?

A ceramic resonator works similar to a crystal. The ceramic resonator utilizes a frequency within the electrical component but unlike the crystal which has a frequency tolerance of 10~30 PPM , a ceramic resonator carries a 0.5% or 5,000 PPM frequency tolerance which is generally used in microprocessor applications where absolute stability is not important.

Here is an easy example to put this into perspective. The percentage difference is similar to an Olympic race. Milliseconds can be the difference between the gold or silver medals. But with an electronic component, the difference is more radical.

Also, crystals utilize hermetically sealed package so they would always be recommended over the ceramic resonators which are environmentally sealed so the crystal is recommended for wide temperature range or harsh environments.
