以太网是全球使用最广泛的局域网技术，而已经被淘汰的拨号上网（ADSL）、十年前左右的宽度上网/猫（PPPOE）、现在的光纤上网/光猫（EPON/GPON）、以及平时所说的交换机（以太网交换机），都属于广域网技术。由于以太网的强大，无线wifi技术也借鉴了以太网的思想，比如wifi中的mac地址，就是来自于以太网；还有wifi跟局域网一样，也是广播类型的网络。所以，无线中也有以太网的身影。
以太网常用的晶振有：具有高精度、小体积、低功耗，极高的性能，1612mm，2016mm，2520mm，3225mm，5032mm，7050mm封装尺寸，-40至+85℃，-40至+125℃超高温度范围，SG3225VEN有源晶振具有高精度，小体积，性能稳定的特点，3225常用封装，-40至+85℃工业级温度范围，能够为以太网提供高效、稳定的性能要求。
