晶振老化怎么辦?

  大家都知道晶振在生產過程中是要經過防老化處理,晶振分為晶體諧振器和晶體振蕩器兩種。在生產晶振過程中,需要分別對兩種晶振進行防老化處理,兩者防老化處理也不相同。晶體諧振器生產完成后,一般需要高溫老化3天。而晶體振蕩器進行老化測試,一般是3天加電,然后測試7天。晶體諧振器比較簡單,晶體振蕩器在加電壓的情況下,要觀察測試記錄,所以比晶體諧振器久一些。

晶振老化怎么辦? 有源晶振的特點?相關問答:

問題:泛音晶體振蕩器的電路構成有什么特點

回答:泛音晶振電路與基波晶振電路的關鍵不同點就是必須含有“抑制基波和低次泛音”的LC諧振回路。

問題:澳门百家乐攻略西勒振蕩器和晶體振蕩器哪個振蕩更穩定

回答:澳门百家乐攻略晶體振蕩器是通常同途中最穩定的……穩定度再高就是原子鐘了

問題:澳门百家乐攻略STM32中,外部晶體振蕩器被旁路是什么意思?這里的旁路怎么理解?

回答:”晶振/時鐘被旁路“ 是指將芯片內部的用于外部晶體起振和功率驅動等的部分電路和XTAL_OUT引腳斷開,這時使用的外部時鐘是有源時鐘或者其他STM32提供的CCO輸出等時

問題:晶體振蕩器怎么用

回答:澳门百家乐攻略一個“晶振”,相當于一個音叉,音叉有一個固有的振蕩頻率,能產生一個固定的音頻,一個“晶振”也具備有一個固定的振蕩頻率,當振蕩電路中選擇使用“晶振”時,也可以使電路產生一個穩定的頻率;如同兩個固有頻率相同的音叉之間可以產生“共振”一樣,當頻率與晶振頻率相同的信號通過晶振時,傳輸的效率最大。

問題:晶體振蕩器,gain margin一般多大

回答:澳门百家乐攻略用matlab畫出傳遞函數的gain圖和相位圖,就可以看出,0db所對應的的相位,以及-180度所對應的的gain。晶體振蕩器是指從一塊石英晶體上按一定方位角切下薄片(簡稱為晶片),石英晶體諧振器,簡稱為石英晶體或晶體、晶振。
