在存储服务器产品设计中搭配BMC控制器须选用一晶振，要求：3225封装、精度不高于±15ppm、工作温度-40至85℃、频点48MHz。笔者推荐了EPSON X1E000021099100，在满足客户基本需求的同时具有更高的频率稳定度（-20 to +75℃可达10ppm）。

图一 X1E000021099100封装、引脚定义及参数

如上可见，X1E000021099100应用于存储服务器BMC时钟设计具有如下优势：

1）频率稳定度可达±10ppm（-20 to +75℃），在存储服务器工作环境下具有更高的时钟精度；

2）典型频率及负载电容客户落实符合现用BMC的时钟设计要求；

3）3225封装符合服务器小封装、自动化的常用设计及生产需求；

4）-40℃到85℃工作温度可较好满足服务器工作环境的应用需求。
