自從推出32.768千赫微型手表晶體已經(jīng)成為有史以來最受歡迎的計(jì)時(shí)參考。這應(yīng)用筆記旨在為的使用提供一些指導(dǎo),計(jì)時(shí)應(yīng)用中的石英晶體，32.768KHz晶振，LFXTAL051643REEL，手表晶振
幾乎在所有情況下，設(shè)計(jì)師都希望使用簡單的邏輯為了方便起見，貼片振蕩器，通常適用于此類設(shè)計(jì)的標(biāo)準(zhǔn)是應(yīng)該是精確的、低成本的和低功耗的。使用一個(gè)手表晶體和CMOS邏輯所有這些標(biāo)準(zhǔn)都可以滿足。
在CMOS振蕩器電路中，功耗隨著頻率而上升因此將工作頻率降低到a是有意義的最低；這就是選擇32.768k的原因。第二種方法降低CMOS電路中功耗的一個(gè)目的是減小尺寸任何被驅(qū)動(dòng)的負(fù)載。部分是因?yàn)檫@個(gè)原因，手表晶體設(shè)計(jì)工作負(fù)載典型值為12.5pF，而非更常見的是20或30pF。它還與:(CMOS的類型有關(guān) 手表中使用的低電壓會(huì)耗盡能量除非使用低晶體負(fù)載電容；(b)保存晶體將電平驅(qū)動(dòng)至低電平，同時(shí)保持足夠的逆變器輸入電壓，以及 (c)允許使用非常小的微調(diào)電容器，同時(shí)仍然提供必要的修整范圍。

可以滿足CMOS倒相振蕩器的基本要求利用單個(gè)柵極和少量其他組件來提供偏置和反饋。圖1顯示了這種類型的典型電路。負(fù)載石英晶體看到的電容是以下電容的串聯(lián)組合 Cout和Cin連同任何電路一起走失，包括邏輯門輸入和輸出引腳電容。中使用的組件值圖1工作良好，并給出了與測量的測試結(jié)果的良好相關(guān)性從Saunders 140晶體阻抗計(jì)獲得。表面現(xiàn)象晶振的負(fù)載電容為: Cout =柵極輸出電容Cin =柵極輸入電容
這給出了6.9pF負(fù)載的數(shù)字。這遠(yuǎn)遠(yuǎn)低于要求圖12.5pF，但是邏輯的輸入和輸出引腳大門呈現(xiàn)出明顯的負(fù)荷。這些附加值需要添加到6.9pF。這些負(fù)載通常在3pF到每個(gè)引腳4pF，但最高可達(dá)10pF，具體取決于邏輯家庭使用。這些額外負(fù)載以及中的雜散電容電路總計(jì)約為12.5pF。

如果需要可微調(diào)振蕩器，22pF輸出電容可以由一個(gè)與2pF至22pF并聯(lián)的固定10pF電容代替微調(diào)器。為獲得最佳結(jié)果，應(yīng)使用NPO、COG或類似的低溫高效電介質(zhì)電容，以獲得最佳穩(wěn)定性。
對(duì)這種振蕩器的一個(gè)經(jīng)常表達(dá)的要求是公差，通常是在沒有規(guī)定的布局中對(duì)于修剪器來說。除了電容容差的影響，還必須意識(shí)到因?yàn)樗鼈兊闹递^低，所以有些可變歸因于IC的阻抗將導(dǎo)致某種程度的不確定性相移，因此振蕩頻率。推薦使用修剪器因此，如果需要優(yōu)于50ppm的精度，而不考慮實(shí)際的晶體公差。
