晶體振蕩器通常是設計師最后考慮的元件之一，但是錯誤的部分可以很快扼殺一個設計。此外，搜索通過各種可用的振蕩器和它們的能力令人困惑。有四個關鍵問題你應該問自己選擇振蕩器。您找到的答案將有助于確保您的滿足設計要求。
你需要晶體還是振蕩器？雖然它們可能看起來完全相同，并且共享許多規格、晶體和振蕩器是非常不同的設備。包裝好的水晶是一塊石英，切割后拋光，以高Q值在特定頻率共振。它沒有包含驅動石英產生時鐘輸出的振蕩器電路。相反，驅動電路位于晶體所在的器件內部已連接。
相比之下，晶體振蕩器(XO)是一個完整的器件，包含石英晶體、振蕩器電路、輸出驅動器和潛在的鎖相環路(PLL)。XO提供特定頻率和信號的時鐘輸出格式，如CMOS、LVDS差分晶振和LVPECL。可以直接驅動芯片或通過緩沖區提供特定頻率。振蕩器是一個完整的單輸出時鐘發生器。大多數消費電子和電池供電應用使用片上系統(SoC) 集成振蕩器電路和簡單、低成本晶體的器件時鐘合成。針對高端應用—數據中心、電信、工業自動化等。—外部XO通常用于提供參考時序用于SoC的內部PLL。
使用片外時鐘源非常有利，因為它提供了獨立、隔離的參考時鐘經過優化，可提供低抖動操作串擾最小。另一個顯著的好處是振蕩器整合了集成電源噪聲抑制，最大限度地降低電路板級的影響時鐘抖動噪聲。

需要什么樣的抖動性能？時序抖動是衡量時鐘信號純度的一種方式。越低抖動，噪音越小。因為振蕩器通常用作本地振蕩器系統的“心跳”,干凈和低抖動的輸出是可取的。抖動可以在示波器的時域中測量，例如周期抖動和逐周期抖動—或在頻域中相位噪聲分析儀，均方根相位抖動在一個頻帶內積分，例如12千赫到20兆赫，
小于250 fs-RMS的低相位抖動XO對于更高性能至關重要因為高水平的時鐘抖動會導致不可接受的高誤碼率(BER)、丟失的通信量或系統通信的丟失。因此，從抖動較低的時鐘源開始總是更安全，以便提供更多抖動余量。在理想情況下，由驅動的應用程序或芯片組振蕩器將提供最大允許抖動規格伴隨的積分頻帶、相位噪聲屏蔽和雜散要求。主要考慮的是需要多大的抖動余量振蕩器允許來自緩沖器或更遠的其它芯片的任何附加抖動在時序路徑的下游，另一個考慮是，一些XO數據手冊只宣傳“典型” 抖動規格。它不能保證器件在整個過程中的性能，電壓、溫度和頻率變化。通常，硬件設計師不會有一套全面的系統所有關鍵元件的抖動要求。參考設計在這種情況下是有幫助的，因為用于設計的振蕩器已經審查過了。
與能提供多種多樣產品的供應商合作也是有幫助的具有不同抖動和成本選項的振蕩器以及在線工具可提供幫助你決定最適合的。同樣，當有疑問時，開始總是更安全低抖動振蕩器，然后評估松弛抖動選項作為降低成本的潛在未來途徑。

你的頻率會變嗎？許多振蕩器應用只需要單一的固定頻率，如156.25 兆赫。在其他情況下，振蕩器提供的頻率可能需要改變。例如，12G-SDI視頻成幀器可能需要在 297MHz和297/1.001 MHz兩種不同的視頻幀速率。在其他時候，可能需要有意增加一個小頻率偏差作為余量測試的一部分，對系統級設置進行壓力測試等待時間。也許最常見的是，設計師可能還不知道確切的，最終設計將使用哪個頻率，但他們知道他們需要一個振蕩器提供這種參考
對于此類應用，理想的解決方案是一個振蕩器，預存頻率。雙通道和四通道振蕩器可用于這些應用程序。這些器件的輸出頻率可通過引腳選擇，從而實現一個XO代替多個振蕩器和一個多路復用器。如果應用需要整數時鐘和小數時鐘的混合，選擇能夠提供一致性能的器件所有目標頻率下的低抖動操作。另一種有用的振蕩器是I2C可編程振蕩器。這些設備提供最大的頻率靈活性，提供一致的低抖動操作在很寬的頻率范圍內。這些設備可以在飛行中重新編程以提供幾乎無限數量的頻率
它們對于原型制作和數字PLL架構中的使用也非常有用，其中主處理器提供快速數字反饋機制鎖定并跟蹤參考信號的XO。

頻率穩定性有多重要？頻率穩定性是衡量振蕩器的輸出頻率由于溫度的變化，在操作過程中可能會發生變化。如果頻率漂移超出應用預期，時序誤差可能發生。頻率穩定性用百萬分率或ppm表示，相對于特定溫度范圍內的標稱頻率。
振蕩器使用在制造過程中以不同角度切割的石英晶體產生不同的溫度反應。普通XO溫度穩定性等級包括20 ppm、50 ppm和100 ppm。較低的ppm意味著在給定溫度范圍內，輸出頻率更加穩定。
值得注意的是，頻率穩定性只是知道如何做到的一個方面振蕩器的頻率可能會改變很多。完整測量潛在的頻率偏差稱為總穩定性，它是整個溫度范圍內的頻率穩定性、25°C時的初始精度和指定的時間和溫度，總穩定性揭示了最壞情況-振蕩器可能產生的頻率超過其工作壽命。
XO在整個溫度范圍內可能具有出色的頻率穩定性，但這測量僅與室內提供的標稱頻率相關溫度。因此，對于某些器件來說，初始精度誤差可能相當大，例如SAW振蕩器，并且必須加以考慮。同樣，石英晶體會在很長一段時間內慢慢老化，從而導致輸出頻率緩慢漂移。一些振蕩器供應商規定了老化時間在25°C下只能存放一年，而更保守的供應商規定存放時間為10年在更高的溫度下工作數年，為長期運營。老化條件會對的總穩定性產生重大影響振蕩器，有時可以進行比較難。當有疑問時，使用有保證的定時裝置更安全更嚴格條件下的規格，以提供更多的設計余量。
