石英晶體諧振器在電子學中的重要性源于它們極高的Q值、相對較小的尺寸和出色的溫度穩定。
石英晶體諧振器利用石英的壓電特性。 直接壓電效應指的是電極化 機械的應用所帶來的某些材料壓力。相反的效果是指產生的變形 通過電場的應用在相同的材料中。在一個石英晶體諧振器，一片薄薄的石英，以適當的角度切割 相對于晶軸的取向位于 兩個電極。施加到這些電極上的交流電壓 導致石英共振。隨之而來的變化 在電極化中構成電位移電流 通過諧振器。
當施加電壓的頻率接近 石英片的機械共振頻率、振幅 振動變得非常大。伴隨的位移 電流也增加，因此器件的有效阻抗 數量減少。阻抗的快速變化 共振附近的頻率變化是關鍵因素 在石英晶體諧振器作為頻率控制的應用中晶體振蕩器中的元件
電學上，石英晶體可以用等效的 圖1的電路，其中串聯組合了R1、L1和C1 代表壓電材料對阻抗的貢獻 效應，C0代表電容之間的分流電容 電極以及任何雜散電容。電感 L1是石英質量的函數，而電容C1是 與它的硬度有關。R1的阻力來自于損失 在石英和安裝裝置中。的參數 等效電路可以測量到1%的精度。 等效電路的電抗-頻率圖如圖所示 2.晶振性能有很多相關的公式；第一 這些是給fs的。這是晶體串聯的頻率 諧振，由下式給出: 其中，fs的單位是赫茲，L1的單位是亨利，C1的單位是法拉。 典型晶體參數值：

校準公差 校準容差是頻率的最大允許偏差 特定溫度下的晶體，參考溫度 (通常為25°C)。
頻率穩定度：晶體不穩定有幾個原因。溫度變動 以及導致長期漂移的質量的物理變化 老齡化可能是我們最關心的問題。 溫度變化的影響通過適當的 晶體切割的選擇和(對于精密公差要求)通過 包括晶體電路中的溫度相關電抗，或者 把它放在一個恒溫的小烤箱里。AT切割晶體 是目前使用最廣泛的，因為它們的頻率溫度曲線系列能以低成本提供良好的性能 除了最苛刻的應用。
未補償的AT切割晶體可以用公差來規定 –10°C至60°C范圍內低至5ppm，要求更大的容差 對于更寬的溫度范圍，如圖3所示 AT切割頻率-溫度曲線的典型系列。這些曲線 可以用三次方程來表示，并且非常依賴于 石英毛坯的切割角度。零度點 系數被稱為上下轉折點。一個轉彎 通過選擇切割角度，可將點放置在需要的位置；這 另一個是固定的，因為兩者都是對稱的 20–30°C范圍。轉折點之間的斜率變為 隨著它們一起移動而變小。晶體設計用于 烤箱被切割，以便上部轉折點與烤箱重合 工作溫度。石英晶體諧振器極高的Q值相對較小的尺寸和出色的溫度穩定

圖4顯示了幾個低頻截點的頻率溫度曲線。J切割在10kHz以下使用，而XY切割可以 從3千赫到85千赫使用。NT-cut可用于10kHz 范圍。DT-cut適用于100kHz至約800kHz，CTcut適用于300kHz至900kHz。
負載電容：晶體可以由制造商在fr校準，其中 它們表現為電阻性(或fs，非常接近fr)，或用于諧振 對于容性負載，它們當然表現為感性。 后一種情況稱為負載諧振，如所示 用符號fL表示的一般術語；更具體地說，符號f30 例如，代表晶體的頻率 30pF容性負載下的諧振。

晶體電抗曲線上校準的點 需要由電路配置決定。作為一名將軍 通常，石英振蕩器中的同相保持放大器需要 fr處的校準，反相放大器需要在某些地方進行校準 “負載電容”值，CL。后一種安排依賴于 電感晶體，以及它所在的負載電容 諧振，以提供進一步的180°相移。
該規則最常見的例外是當一個小電容， 例如，變容二極管與晶體串聯 非反相放大器電路提供一定程度的頻率 調整。在這種情況下，必須校準晶體 與該電容的平均值共振。
可拉性：晶體的可拉性是其頻率變化的量度 負載電容的給定變化。這通常表示為 其串聯諧振頻率(fr)與其負載之間的差異 共振頻率(fL)。該偏移可以用每分鐘的部分來計算 百萬使用分數負載諧振頻率偏移(DL) 對于給定的CL值，實際頻率從fr變化到fL。
其中C1、C0和C1都用相同的單位表示。 圖5顯示了頻率變化影響的典型曲線 關于負載電容的變化。 或者，通常將晶體的可拉性表示為切邊 負載電容變化的靈敏度，單位為ppm/pF。這是在 ppm/pF由: 其中C1、C0和CL以pF為單位，如圖6所示 對于(C0 + CL)的各種值。石英晶體諧振器極高的Q值相對較小的尺寸和出色的溫度穩定

頻率穩定度：晶體不穩定有幾個原因。溫度變動 以及導致長期漂移的質量的物理變化 老齡化可能是我們最關心的問題。 溫度變化的影響通過適當的 晶體切割的選擇和(對于精密公差要求)通過 包括晶體電路中的溫度相關電抗，或者 把它放在一個恒溫的小烤箱里。AT切割晶體 是目前使用最廣泛的，因為它們的頻率溫度曲線系列能以低成本提供良好的性能 除了最苛刻的應用。
未補償的AT切割晶體可以用公差來規定 –10°C至60°C范圍內低至5ppm，要求更大的容差 對于更寬的溫度范圍，如圖3所示 AT切割頻率-溫度曲線的典型系列。這些曲線 可以用三次方程來表示，并且非常依賴于 石英毛坯的切割角度。零度點 系數被稱為上下轉折點。一個轉彎 通過選擇切割角度，可將點放置在需要的位置；這 另一個是固定的，因為兩者都是對稱的 20–30°C范圍。轉折點之間的斜率變為 隨著它們一起移動而變小。晶體設計用于 烤箱被切割，以便上部轉折點與烤箱重合 工作溫度。石英晶體諧振器極高的Q值相對較小的尺寸和出色的溫度穩定
圖4顯示了幾個低頻截點的頻率溫度曲線。J切割在10kHz以下使用，而XY切割可以 從3千赫到85千赫使用。NT-cut可用于10kHz 范圍。DT-cut適用于100kHz至約800kHz，CTcut適用于300kHz至900kHz。
負載電容：晶體可以由制造商在fr校準，其中 它們表現為電阻性(或fs，非常接近fr)，或用于諧振 對于容性負載，它們當然表現為感性。 后一種情況稱為負載諧振，如所示 用符號fL表示的一般術語；更具體地說，符號f30 例如，代表晶體的頻率 30pF容性負載下的諧振。

該規則最常見的例外是當一個小電容， 例如，變容二極管與晶體串聯 非反相放大器電路提供一定程度的頻率 調整。在這種情況下，必須校準晶體 與該電容的平均值共振。
可拉性：晶體的可拉性是其頻率變化的量度 負載電容的給定變化。這通常表示為 其串聯諧振頻率(fr)與其負載之間的差異 共振頻率(fL)。該偏移可以用每分鐘的部分來計算 百萬使用分數負載諧振頻率偏移(DL) 對于給定的CL值，實際頻率從fr變化到fL。
其中C1、C0和C1都用相同的單位表示。 圖5顯示了頻率變化影響的典型曲線 關于負載電容的變化。 或者，通常將晶體的可拉性表示為切邊 負載電容變化的靈敏度，單位為ppm/pF。這是在 ppm/pF由: 其中C1、C0和CL以pF為單位，如圖6所示 對于(C0 + CL)的各種值。石英晶體諧振器極高的Q值相對較小的尺寸和出色的溫度穩定
