IC6 is an SMSC 10/100 Ethernet PHY, with its associated 25 MHz oscillator. The PHY
requires an Ethernet MAC implemented within the FPGA.
J19 is the RJ-11 Ethernet connector associated with the 10/100 Ethernet PHY.
See Chapter 14, “10/100 Ethernet Physical Layer Interface,” for additional information.
