The board supports Gigabit Ethernet transfer by an external Micrel KSZ9021RN PHY chip and
HPS Ethernet MAC function. The KSZ9021RN chip with integrated 10/100/1000 Mbps Gigabit
Ethernet transceiver also supports RGMII MAC interface. Figure 3-31 shows the connections
between the HPS, Gigabit Ethernet PHY, and RJ-45 connector.
The pin assignment associated to Gigabit Ethernet interface is listed in Table 3-24. More
information about the KSZ9021RN PHY chip and its datasheet, as well as the application notes,
which are available on the manufacturer’s website.
