关于晶体振荡器的时钟精度(Clock Accuracy)的两个指标
关于晶体振荡器的时钟精度(Clock Accuracy),说明如下: 时钟精度是衡量理论频率值和实际采样频率值之间差异的一个指标。通常情况下,工程师用“百万分之一”(ppm)来表示频率精度,同时至少还要加上一个工作温度范围。如: 工作温度(Operating Temperature Range):-…时间:2023/03/29 -

如何提高晶振输出的频率精度?
如何提高晶振输出的频率精度?晶诺威科技解释如下: 首先,晶振分为无源晶振(晶体谐振器)和有源晶振(晶体振荡器)两种。无源晶振的输出频率精度可微调,而有源晶振的频率输出精度不可调。 通常,晶振输出的时钟精度是由其本身频率精度所决定,外部条件的改变并不能大幅度提高晶振输出频率精度,一般要更换更高精度的晶…时间:2023/02/09 -
