2.4.3 10/100 Ethernet PHY via Texas Instruments DP83848J PHY and TE Connectivity RJ45 connector
The PHY device is a Texas Instruments DP83848J. The TE Connectivity RJ45 connector includes integrated
magnetics and LEDs.
A MAC must be placed inside the FPGA, such as the AXI Ethernet Lite, AXI Tri-Mode Ethernet Media
Access Controller (TEMAC), XPS Ethernet Lite, or XPS Tri-Mode TEMAC. These cores are accessible in
ISE Embedded or EDK. The TEMACs require the purchase and installation of a license.
