晶振的功能是為系統(tǒng)提供基本的時(shí)鐘信號(hào)，通常一個(gè)系統(tǒng)共用一個(gè)晶振，便于各部分保持同步。有些通訊系統(tǒng)的基頻和射頻使用不同的晶振，不同的規(guī)格封裝延伸很多的頻點(diǎn)等不同的參數(shù)，而通過電子調(diào)整頻率的方法保持同步，在我們?nèi)粘Ｉ钪幸搽x不開貼片晶振.時(shí)鐘振蕩器是利用了晶體的壓電效應(yīng)制造的,當(dāng)在晶片的兩面上加交變電壓時(shí)，晶片會(huì)反復(fù)的機(jī)械變形而產(chǎn)生振動(dòng)，而這種機(jī)械振動(dòng)又會(huì)反過來產(chǎn)生交變電壓。GPS定位系統(tǒng)專用晶振CWX815-32.768MHz/7050mm/5V/CMOS/±25ppm/SMD
