Hi,
I was reading OnSemi's AN8173 app note and couldn't understand why common mode voltage of AC coupled line is equal to VTERM.
My thought was each input of the receiver will swing between VTERM and VTERM-400mV, thus the common mode would be VTERM-200mV.
I think there's something I am missing understanding the circuit.
Can anyone explain why input swings are between VTERM+200mV and VTERM-200mV?
Thanks
