Intel Arria 10 - 10 GBASE-R, 10 GBASE-R with IEEE 1588 V2, and 10 GBASE-R with FEC; Variants

2.6.2. 10GBASE-R, 10GBASE-R with IEEE 1588v2, and 10GBASE-R with
FEC Variants
10GBASE-R PHY is the Ethernet-specific physical layer running at a 10.3125-Gbps
data rate as defined in Clause 49 of the IEEE 802.3-2008 specification. Arria 10
transceivers can implement 10GBASE-R variants like 10GBASE-R with IEEE 1588v2,
and with forward error correction (FEC).
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
10GBASE-R is a single-channel protocol that runs independently. You can configure
the transceivers to implement 10GBASE-R PHY functionality by using the presets of
the Native PHY IP. The 10GBASE-R PHY IP is compatible with the 10-Gbps Ethernet
MAC Intel FPGA IP Core Function. The complete PCS and PHY solutions can be used to
interface with a third-party PHY MAC layer as well.
