2.15 Ethernet Interface

The AM62x SIP SK EVM offers two Ethernet Ports of 1 Gigabit Speed for external Communication. Two channels of RGMII Gigabit Ethernet CPSW Ports from AM62x SIP SoC are connected to separate Gigabit Ethernet PHY Transceivers DP83867, which are finally terminated on two RJ45 connectors with integrated magnetics.

The 48pin version of the PHY DP83867 is configured to advertise 1-Gb operation with the internal delay set to accommodate the internal delay inside the AM62x. CPSW_RGMII1 and CPSW_RGMII2 Ports share a common MDIO Bus to communicate with the external PHY Transceiver.

Two Single port RJ45 Connectors Mfr Part# LPJG16314A4NL from Link-PP are used on the board for Ethernet 10/100/1G Connectivity. RJ45 Connectors have integrated magnetics and LEDs for indicating 1000BASE-T link as well as receive or transmit Activity.

IOsupply to the Ethernet PHY is set 3.3V level.
