晶科鑫将在本文介绍晶振的作用及晶振电路的PCB设计注意事项。晶振被誉为“电子设备的心脏”，它是电子产品中最常用的不可或缺的被动器件，小到手表、电脑，大到航空母舰、卫星都需要晶体振荡器。晶体振荡器是指从一块石英晶体上按一定方位角切下薄片（简称为晶片），石英晶体谐振器，简称为石英晶体或晶体、晶振，而在封装内部添加 IC 组成振荡电路的晶体元件称为晶体振荡器。其产品一般用金属外壳封装，也有用玻璃壳、陶瓷或塑料封装的。

晶振的作用

晶振是时钟电路中最重要的部件，它的主要作用是向显卡、网卡、主板等配件的各部分提供基准频率，它就像个标尺，工作频率不稳定会造成相关设备工作频率不稳定，自然容易出现问题。在通常工作条件下，普通的晶振频率绝对精度可达百万分之五十，高级的精度更高。

晶振的另一个作用是为系统提供基本的时钟信号。通常一个系统共用一个晶振，便于各部分保持同步。有些通讯系统的基频和射频使用不同的晶振，而通过电子调整频率的方法保持同步。

晶振电路的PCB设计

1、位置要选对：晶振内部是石英晶体，如果不慎掉落或受不明撞击，石英晶体易断裂破损，所以晶振的放置远离板边，靠近MCU的位置布局。

2、两靠近：耦合电容应尽量靠近晶振的电源管脚，如果多个耦合电容，按照电源流入方向，依次容值从大到小摆放；晶振则要尽量的靠近MCU。

3、走线短：所有连接晶振输入/输出端的导线尽量短，以减少噪声干扰及分布电容对晶振的影响。

4、高独立：尽可能保证晶振周围的没有其他元件。防止器件之间的互相干扰，影响时钟和其他信号的质量。晶振周围 1mm 禁布器件，0.5mm 禁布过孔走线，所有晶振下不打过孔（包括地过孔）。

5、外壳要接地：晶振的外壳必须要接地，除了防止晶振向外辐射，也可以屏蔽外来的干扰。

【经验】解析手表不准的原因，可能是水晶振子出问题了

石英水晶振动子在日本晶体行业中是常叫的一种关键词,有时候也叫水晶振子，就像晶科鑫公司在中国叫晶振一样，因此这两个名词是相同的意思，只是地域不同影响叫法不同，晶科鑫官网有个专栏”晶振百科”是介绍晶振的所有知识，大家有兴趣的话可以多了解有关晶振的知识。

晶振的品质对智能马桶的影响

晶振为智能马桶提供稳定的时钟信号。智能马桶作为一个集成了多种功能的智能家居产品，需要精确的时钟信号来确保各项功能的正常运行。晶振以其高频率稳定性和准确性，为智能马桶提供了可靠的时钟基准，从而保证了马桶内部各个系统之间的同步和协调。
