Hello All,

I need a help about connection between PHY modes.... I hav attached a pdf in which there are 10UF caps which are connected between RX and TX of each port.. Now I want to know is, Normally a cap acts as a open switch for DC voltages. But since there are differential voltages in RX and TX pins,How will these caps work. Why are these caps placed in between these transmission lines.

Please guide me on the same.

Thanks and Regards

Nikhil
