Is this is licensed core? After discussing with the ASIC team: The vendor IP in our ASIC performs a parallel GMII to serial SGMII translation, including clock recovery and framing. It implements the entire IEEE 802.3z PCS and is managed with a MCD/MDIO serial interface. The SGMII interface connects to an external PHY (and the external PHY is managed with a separate MDIO interface). Thanks, -Nick Hawkins
