LVDS（Low Voltage Differential Signaling)它是一种低摆幅的差分信号技术，它使得信号能够在差PCB线对或平衡电缆上以几百的Mbps的速率传输，其低压幅以及低电流驱动输出实现了低噪声以及低功耗。LVDS（Low Voltage Differential Signaling）是一种小振幅差分信号技术，LVDS信号传输一般由三部分组成：差分信号发送器，差分信号互联器，差分信号接收器。

LVDS差分输出晶振我们可以称为是一种低电压差分信号，主要就是一种低功耗、低误码率、低串扰和低辐射的差分信号技术。其中LVDS的核心技术主要是采用了一种非常低的电压摆幅高速差来传输数据，实现点对点或者点对多的连接，传输的介质一般是pcb连线或者平衡电缆。
