带压控功能的晶振EFC Linearity指的是什么?
答:指的是“Electronic Frequency Control ”,即:电子频率控制(EFC)系统输入与输出之间的线性关系,一般为10%。
EFC Linearity refers to the linear relationship between the input and output of an Electronic Frequency Control (EFC) system. It indicates how well the EFC input works and how consistent the output is across different levels of input. In the context of EFC, measuring linearity helps ensure that the system operates efficiently and accurately, allowing for precise control in applications such as crystal oscillators.
EFC线性度指的是电子频率控制(EFC)系统输入与输出之间的线性关系。它表明了EFC输入的效能如何,以及在不同输入水平下输出的一致性如何。在EFC的语境中,测量线性度有助于确保系统高效准确地运行,从而在诸如晶体振荡器等应用中实现精确控制。
由上图容易看出:EFC呈现正比关系(EFC电压的升高导致频率的升高,EFC在本质上是线性的,但仔细检查会发现它并不完全线性。
