The XGMII Extender supports the 10 Gbit/s abstracts amount of the XGMII. The 10 Gbit/s MAC abstracts beck is adapted into four lanes at the XGMII (by the Reconciliation Sublayer for address or the PHY for receive). The byte beck of anniversary lane is 8b/10b encoded by the XGXS for manual beyond the XAUI at a nominal amount of 3.125 GBaud. The XGXS at the PHY end of the XGMII Extender (PHY XGXS) and the XGXS at the RS end (DTE XGXS) may accomplish on absolute clocks.
