2.6.3 XFI 10GBase-T port support
The T2080 only supports evaluation of the XFI protocol using Aquantia AQ1202 dual
port 10GBase-T PHY. 10G data is carried over the XFI interface. The image below
shows the connectivity of XFI interface.

2.6.4 SATA support
SATA is evaluated using the two onboard SATA headers, by selecting a SATA-
supporting SerDes protocol.
2.7 Ethernet controllers
The T2080 supports two Ethernet Controllers (EC), which can connect to Ethernet PHYs
using MII or RGMII protocols. On the T2080RDB-PC, the EC1 and EC2 ports only
operates in RGMII mode. Both ports connect to Realtek RTL8211 PHYs.
The image below shows the connectivity of EC1/EC2 interface.
