【选型】晶光华无源晶振可PTP兼容村田XRCGB0M000F1S1CR0,误差精度高可达±10ppm
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。
