低功耗晶体振荡器X1G004481012800适用于千兆以太网应用

石英晶体振荡器（以下简称晶振）是利用石英晶体压电效应而制成的器件，它的作用是输出高精度和高稳定度的脉冲信号，为整个电路提供时序基准。我们知道，现在电路中有越来越多的时序电路，它们之间的协同运行必须要有一个时间基准，才能统一一致的行动，就像电视剧里特种行动小队在出发前都要对下表一样，晶振在系统中起的作用就如同队长的手表，它如果稳定性或准确性不好的话，那整个系统就会错误频出，故障率很高。所以又把晶振称为单板的“心脏”。石英晶体振荡器是由品质因数Q极高的石英晶体谐振器和振荡电路组成。晶体的品质因数、切割取向、晶体振子的结构及电路形式等，共同决定振荡器的性能。国际电工委员会（IEC）将石英晶体振荡器分为4类：普通晶体振荡（SPXO），电压控制式晶体振荡（VCXO），温度补偿式晶体振荡（TCXO），恒温控制式晶体振荡（OCXO）。目前发展中的还有数字补偿式晶体振荡（DCXO）以及混合式的VOCXO振荡等。
