Ethernet
The processor provides two Ethernet ports, connected via RGMII links to two
Marvell 88E1512 PHYs, as shown below. A further two, optional Ethernet ports are
provided by two Intel I210 Ethernet Controller devices accessed via the PCIe
switches.
Figure 4-4 Ethernet PHY Block Diagram
The PHYs are isolated from the backplane using transformer-coupled magnetics.
The Ethernet ports are mapped to processor Datapath Tri-Speed Ethernet Controller
(dTSEC) interfaces within Frame Manager 2 as shown below:
