The AM571x IDK EVM contains two Gigabit (1000Mb) Ethernet PHY/Transceivers (KSZ9031RN) interfaced to connectors J10 (RGMII0) and J12 (RGMII1). These Gigabit Ethernet transceivers are connected over RGMII0 and RGMII1 to the Ethernet switch block within the AM5718 processor.
The resets for the transceivers are driven low coincident with the PORz reset to the AM5718 processor. A 25-MHz clock is provided into each of the KSZ9031RN Gigabit transceivers.
