  綜上所述,工程師們在選購的時候不僅僅要考慮晶振頻率,還要考慮封裝、負載、精度、頻點以及工作溫度等因素要綜合價格方面選擇最優產品了。晶振是單片機里很重要的一個元器件,如果沒有了晶振,單片機也就無法正常工作。晶振是單片機的心臟,有了晶振才能為單片機系統提供時鐘信號,使其正常運轉。

單片機晶振有哪些參數?單片機沒晶振會怎樣?相關問答:

問題:如何擴大晶體壓控振蕩器的頻率控制范圍

回答:您好,可以采用不同負載電容(CL)的晶體試用。試用晶體具有較低電容若頻率比目標頻率超高很多的話。請檢查波形幅度是否是正常或不使用示波器,正確的電容是通過和頻率調節到目標之

問題:40MHz晶體振蕩器的價格

回答:澳门百家乐攻略40MHZ晶體0.5元一支。 如果是特別定制的話,價格另有不同

問題:澳门百家乐攻略什么是石英晶體振蕩器

回答:石英晶體振蕩器又名石英諧振器,簡稱晶振,是利用具有壓電效應的石英晶體片制成的。這種石英晶體薄片受到外加交變電場的作用時會產生機械振動,當交變電場的頻率與石英晶體的固有

問題:澳门百家乐攻略晶體振蕩器6腳的價格比4腳的是不是貴好多?

回答:常規來講晶體振蕩器價格是高些,4腳石英晶體振蕩器較為常用生產量多價格就比6腳的要便宜些了。

問題:澳门百家乐攻略石英晶體振蕩器的輸出頻率

回答:它有兩種頻率,一種為串聯諧,另一種為并聯諧振頻率,后者高于前者,但在實際使用中,晶振上標的頻率數即為其輸出頻率.
