针对晶振频率年老化率Frequency Aging，我司解释如下：

首年晶诺威科技产晶振产品老化率小于±3PPM（1st year首年），随后趋于稳定，每年老化率低于±3PPM。通过充分试验及验证，晶振频率在1000小时之后就会趋于稳定状态。

以贴片无源晶振SMD3225 24.576M为例，频率稳定性变化测试数据图如下，请参考：

NOTE:

Aging is estimated from environmental reliability tests and the expected amount of frequency variation over time. It is not intended as a guarantee of performance over the product-life cycle.
