什么是晶振的温度特性？

时间： 2024-01-31 来源：星通时频官网

晶振的温度特性漂移速度以及漂移量取决于晶振所处的环境温度点、环境的温变速度、设备机箱的温度传递速度以及晶体的迟滞特性，晶振频率漂移与温度变化的关系类似于一个加速阻尼振荡，是个5次函数关系，而温度传感器对于温度变化的响应速度是非常快的，如要简单依赖温度传感器对石英晶体谐振器的温度特性做优化，会带来温度补偿超前或滞后，导致频率晃动加上，短稳、抖动指标都将恶化，而且优化系统很难预知其他温度点晶振的漂移值。

晶振的工作温度范围是技术条件中所规定的温度范围，在该温度范围内，晶振的性能应满足技术要求。可工作温度范围是技术条件中规定的温度范围，在该温度范围内，晶振能连续输出信号，但其性能不一定满足技术要求。频率温度特性是指环境温度在规定的范围内按预定的方式改变时，其输出频率产生的相对变化特性。

【技术】一文带你详细了解主板时钟晶振的种类及作用

晶振是由石英晶体切割而成的引线，在通电的时候具备一个非常显著的功能，那就是能够发生机械震荡。时钟振荡器是利用了晶体的压电效应制造的，当在晶片的两面上加交变电压时，晶片会反复的机械变形而产生振动，而这种机械振动又会反过来产生交变电压。

差分晶振电气参数简介

差分晶振全称是Differential Output Crystal Oscillator，高频差分多路输出的振荡器。差分晶振是一种输出差分信号的有源晶振，差分信号输出2路相位完全相反的信号，从而消除2个信号的共模噪声，产生一个更高稳定性能的系统。本文星通时频介绍差分晶振电气参数。
