The MAC signals have to travel through SERDES, PCS layer and the rate adaptation blocks of the PHY. For instance, in the transmit direction, the differential pair transmit and transmit-clock signals are de-serialised and passed through PCS to recover the SGMII signals. This then passes through the rate adaptation block to output the data at the Ethernet port speed. > 2).
