笔记本电脑主板上的晶振出了问题,会对电脑带来什么影响?
电脑主板上晶振的主要作用是为了产生时钟频率,这个原始的时钟频率经过频率放大器的放大或缩小后就成了电脑中各个总线的频率。以声卡为例,要实现对模拟信号44.1kHz或48kHz的采样,频率发生器就必须提供一个44.1kHz或48kHz的时钟频率。如果需要对这两种音频同时支持的话,声卡就需要有两颗晶振。主板上的晶振还有个作用是在电路产生振荡电流,发出时钟信号。
主板晶振非常重要,主板的晶振坏了,通常表现为不能开机、启动显示器无反映、黑屏、开机后关机等故障。
通常电脑主板上用到的晶振有以下几种
32.768kHz晶振:主要用于实时时钟(RTC)模块,用于计算机系统的时间管理。推荐选用应达利的SMLF-3215系列(料号:9CAA32768122TF70QT),SMLF-1610(32.768KHz)等低频音叉晶体。
12MHz晶振,现在的部分主板上出现了12M的晶振,这款晶振主要用于USB接口。若有损坏,则可能导致USB接口失灵等问题。
14.318MHz时钟晶振,用于时钟芯片。14.318MHz晶振不起振,会影响主板上电后全板无复位。起振波形不正常,还有可能导致主机开机不稳定的现象发生。
24.576MHz音频晶振,与声卡芯片相连。晶振不起振可能会出现无音频信号,抓不住声卡等问题。
25MHz晶振,与网卡芯片相连,晶振不起振会影响不上电,或上电后断电或不开机现象,单边起振也出现上电后断电现象。而用于网卡芯片时,不起振则会抓不到网卡,频率异常会出现不连网或网灯不亮等现象。
27MHz晶振,为BGA内部VGA部分提供相关工作时钟,27M晶振不起振则会影响VGA无显示。

YXC无源晶振【选型篇】
晶振是一种能够产生时钟频率信号的关键元件。无源晶振的工作原理基于石英的压电效应。在石英水晶片的两边镀上电极,当在两电极上加一定的电压时,由于石英的压电效应会产生形变,从而给IC提供一个正弦波形。这个正弦波形经过IC的内部整形和PLL(锁相环)电路后,产生方波,然后输入给下级电路。无源晶振必须结合外围电路构成一个振荡器才能输出特定频率的信号,而这个振荡器需要外部电源提供驱动电流。
