爱普生发布首款优质的LVPECL差分晶振X1G005221000200，5G网络建设作为当前最佳的赛道，正在加速发展与推进，随着5G网络进入了发展的快车道，5G相关的有源晶振也成了当下的一个缺口，在电子行业的市场，能够满足5G应用市场的要求，并不算太完善，并且有大量的机会，很适合选择相关的晶振产品开拓起来.5G专网是利用5G无线通信技术组建专用网络，为垂直行业提供高性能通信服务的一种技术方案。

石英晶体振荡器就是我们俗称的有源晶振，可以很好适应5G通信的需求，这是一种由石英晶体（二氧化硅晶体）的压电效应制成的谐振器件。 其基本结构如下：在一定方位角（称为晶圆，可以是方形，矩形或圆形）切片一块石英晶体，并将其涂在两个相应的表面上。 银层作为电极，每个电极上焊接一根引线连接到引脚，并加入封装壳体，形成石英晶体谐振器，简称石英晶体或晶体，简称晶体振荡器。 由IC构成的振荡电路的晶体元件称为晶体振荡器。 其产品通常包装在金属外壳中，也可以包装在玻璃外壳，陶瓷或塑料中。
