H，
使用交流耦合时，您仍需要一个终点，并且需要在接收器处设置共模电压。
一种方法是通过接收器上的51欧姆电阻将每个输入（+， - ）终止为Vcm = 1.2v。
或者，您可以使用内部100欧姆端接，并通过10K电阻将每个+， - 连接到Vcm（外部电阻的信号完整性问题更少 - 只是偏置）。

h,
With AC coupling, you still need a termiantion, and you need to set the common mode voltage at the receiver. One way is to terminate each input (+, -) to Vcm = 1.2v each through a 51 ohm resistor at the receiver. Or, you could use the internal 100 ohm termination, and connect each +,- through a 10K resistor to the Vcm (less signal integrity issues with the external resistors -- just biasing).
