Ethernet

MYD-AM335X-Y integrates two Ethernet interface. As shown in Figure 3-2, Ethernet interface 1 or Ethernet interface 2 are GMII interface, translate into physical layer signal by two PHY chips, and then output Gigabit signals by connecting to the integrated block RJ45. Two PHY chips, one is integrated in the MYD-AM335X-Y core board, another is located on the MYB-AM335X-Y floor.
