在工作电路中，如果晶振损坏会有哪些特征现象呢？晶振损坏分为两大类，一是彻底停振，二是具有不稳定性。晶振厂商应达利电子股份有限公司带您看看如何处理：

彻底损坏时，可将其拆下，与正常同型号集成电路对比测其每一引脚对地的正、反向电阻，总能找到其中一只或几只引脚阻值异常。

具有不稳定性，引起不稳定性的原因有很多，可能是晶振质量问题，更多原因则是晶振参数与电路参数不相匹配，例如系统要求精度20ppm，而晶振参数只有50ppm；再或者匹配电容要求12PF，而实际电容只有9PF诸多原因。那么需要算出正确电容匹配值更换晶振，或者是更换电容。更换精度合适的晶振，如果是其它问题引起的不稳定，用无水酒精冷却被怀疑的集成电路，如果故障发生时间推迟或不再发生故障，即可判定。通常只能更换新集成电路来排除。

主板常用的晶振规格有哪些呢？

常用频率：

32.768kHz：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9CAA32768（3215封装，32.768KHz），SMLF-1610（32.768KHz）等低频音叉晶体。

14.318MHz：主要用于显卡和其他视频相关设备的时钟信号。推荐选用应达利的5YAA14318（14.318MHz）贴片晶振。

24MHz、25MHz、26MHz：主要用于主板芯片组、CPU和其他设备的时钟信号。推荐选用应达利SMCE-2016（16MHz~96MHz）定制频率贴片晶振。

常用封装尺寸：

1.2x1.0mm，1.6x1.2mm，2.0x1.6mm：适用于对体积要求较高的场合，如可穿戴设备、智能手机等消费电子产品。

3.2x2.5mm：适用于对性能和体积要求适中的场合，如平板电脑、数据中心服务器等。

5.0x3.2mm：适用于对性能要求较高的场合，如工业控制、通信设备等。
