AC-coupling capacitors for high-speed differential interfaces
Any AC coupling capacitor that you place in your signal line is going to be a lower impedance point and will therefor cause a negative reflection back to the source. Whether or not this reflection will come back and then interfere with other bits is determined by the speed of your signal and the distance of this reflection point from your transmitter.
