The transceivers do not support the XGMII interface to the MAC/RS as defined in the IEEE 802. Sublayers (XGXS) to extend the reach of the XGMII for 10 Gb/s operation. A separate APB interface allows the host applications to configure the Controller IP for Automotive. 4. Several Physical Coding Sublayers known as 10GBASE-X, 10GBASE-R, and10GBASE-W are specified, as well as significant additional supporting material for a 10 GigabitMedia Independent Interface (XGMII), a 10 Gigabit Attachment. 7. 4. interface.
