晶振频率稳定性(Frequency stability)都包括什么?
答:晶振频率稳定性包括以下条件引起的频率变化之总和:
工作温度、负载变化、额定输入(电源)电压变化、初始校准容差(25°C)、老化(在25°C平均有效环境温度下1年)、冲击和振动。
举例:某款展频晶振频率稳定性如下:
英文解释如下:
Stability includes all combinations of operating temperature, load changes, rated input (supply) voltage changes, initial calibration tolerance (25°C), aging (1 year at 25°C average effective ambient temperature), shock and vibration.
