User guide

The 10GBASE-R parallel data interface is the 10 Gigabit Media Independent Interface (XGMII) that
interfaces with the Media Access Control (MAC), which has the optional Reconciliation Sub-layer (RS).

Legend
You can configure the transceivers to implement 10GBASE-R PHY functionality by using the preset of
the Native PHY IP. The 10GBASE-R PHY IP is compatible with the Altera 10-Gbps Ethernet MAC
Megacore Function. The complete PCS and PHY solutions can be used to interface with a third-party
PHY MAC layer as well.
