维管晶振补偿网络驱动牵引网络,调整振荡器的频率

来源:http://www.yijindz.com 作者:亿金电子 2022年05月18
    实现这一目标的方法随着时间的推移而发生了变化。最早使用的方法之一是直接补偿技术,其中使用热敏电阻、电容器和电阻器网络直接控制振荡器的频率。温度的变化会导致热敏电阻发生变化,从而导致网络的等效串联电容发生变化——这反过来会改变晶体上的电容负载,从而导致频率的变化振荡器

    当前的方法将补偿网络和拉动网络集成到一个集成电路中,补偿网络的作用由一组运算放大器发挥作用,这些运算放大器相加在一起会在整个温度范围内产生3阶或5阶函数。与间接补偿方法一样,该电压用于驱动变容二极管,进而改变振荡器的输出频率。由于晶体特性的变化意味着不存在“一刀切”的功能,因此该解决方案是在TCXO的温度测试期间得出的。使用两个电容阵列将室温下的频率调整到标称值,然后在测试过程中获得温度补偿功能所需的设置并存储在片上存储器中。

    TCXO晶振对工程师很有用,因为它们可以在任何地方获得比标准VCXO高10倍到40倍的温度稳定性,同时具有相同的功耗和电路板上的占位面积。TCXO弥合了标准XO或VCXO与OCXO之间的差距,后者更昂贵且需要更多功率才能运行。技术的推动力是降低功耗,当然还有降低成本,因此TCXO为功率和成本敏感的应用提供了良好的中档解决方案。
