Question:

Hello, I have a question! Which values are better in terms frequency stability? Higher or lower? Comparing a 0.5ppm to a 1.5ppm?

你好，我有一个问题！晶振频率稳定性这个数值怎么看？越低越好,还是越高越好？比较±0.5ppm和±1.5ppm?

Answer:

Lower is usually better. As this signifies a lower frequency variation.

通常越低越好,因为这意味着晶振输出的频率有较小的变化，即，稳定度更好。若比较±0.5ppm和±1.5ppm，显然±0.5ppm稳定度更好。
