技术问答

在蓝牙dongle中，需要一颗晶振给蓝牙主控提供一个工作的时钟信号，就需要用到一颗高精度的晶振，市场上由于国外品牌的晶振缺货，寻找国产替换的也是一种选择。下面主要介绍晶光华 S2140000091070JY P2P替换村田XRCGB0M000F1S1CR0可行性分析，以便解决缺货问题，参数性能对比如下。

一、pin脚对比

从上面的pin脚对比图可以看出，晶光华S2140000091070JY和村田XRCGB0M000F1S1CR0封装都是2016，管脚功能也相同，1、3脚为信号脚，2、4为GND。

二、参数表对比

S2140000091070JY：

XRCGB0M000F1S1CR0：

从上面的2个对比表中可以看出，晶光华 S2140000091070JY和村田XRCGB0M000F1S1CR0的频率都是40MHZ，误差精度都是±10ppm，工作温度范围晶光华 S2140000091070JY为-40-85℃优于村田XRCGB0M000F1S1CR0。综上所述，晶光华 S2140000091070JY和村田XRCGB0M000F1S1CR0封装相同都是2016，频率和误差精度相同，所以，晶光华 S2140000091070JY可以P2P兼容村田XRCGB0M000F1S1CR0。

晶光华 S2140000091070JY优点，误差精度高可达±10ppm，工作温度范围宽可达-40-85℃，能P2P兼容村田XRCGB0M000F1S1CR0，是选择国产替换的一种不错的选择。
