32.768kHz晶振电路分析与设计

振荡电路用于实时时钟RTC时，经常使用爱普生FC-135/135R贴片音叉晶振或者C2系列圆柱体晶振（32.768kHz的晶体谐振器）连接在OSC3 与OSC4之间而且为了获得稳定的频率必须外加两个带外部电阻的电容以构成振荡电路。当然，还可以使用内嵌振荡电路的SG7050EAN系列32.768kHz晶

选型与应用

为什么要用内置晶体的实时时钟芯

实时时钟（RTC）可独立完成计时或事件记录的功能。目前很多电子产品都具有时钟计时功能，而且对时钟的精度要求越来越高。RTC 产品种类繁多，根据封装尺寸、接口方式、附加功能、时钟精度、待机功耗等进行分类。产品结构上又可分为内置晶体和外置晶体两种。
