低功耗晶體振蕩器X1G004481012800適用于千兆以太網應用

石英晶體振蕩器（以下簡稱晶振）是利用石英晶體壓電效應而制成的器件，它的作用是輸出高精度和高穩定度的脈沖信號，為整個電路提供時序基準。我們知道，現在電路中有越來越多的時序電路，它們之間的協同運行必須要有一個時間基準，才能統一一致的行動，就像電視劇里特種行動小隊在出發前都要對下表一樣，晶振在系統中起的作用就如同隊長的手表，它如果穩定性或準確性不好的話，那整個系統就會錯誤頻出，故障率很高。所以又把晶振稱為單板的“心臟”。石英晶體振蕩器是由品質因數Q極高的石英晶體諧振器和振蕩電路組成。晶體的品質因數、切割取向、晶體振子的結構及電路形式等，共同決定振蕩器的性能。國際電工委員會（IEC）將石英晶體振蕩器分為4類：普通晶體振蕩（SPXO），電壓控制式晶體振蕩（VCXO），溫度補償式晶體振蕩（TCXO），恒溫控制式晶體振蕩（OCXO）。目前發展中的還有數字補償式晶體振蕩（DCXO）以及混合式的VOCXO振蕩等。
