Place termination resistors RX_D0-3, RX_ER, RX_DV, RX_CLK, TX_CLK, CRS, COL, RSTN as close to the G-PHY as possible using 50 ohm impedence traces.
Place termination resistors TX_D0-3, TX_ER, TX_EN, GTX_CLK as close to FPGA as possible using 50 ohm impedence traces.
MH1 and MH2 are 0.100" diameter plated through holes
Ethernet RJ45 Connector
Place caps close to RJ45 jack
TX and RX traces are all matched length < 2"
SFP Connections not used
