Place termination
resistors RX_D0-7,
RX_ER, RX_DV, RX_CLK,
TX_CLK, CRS, COL
as close to the
G-PHY as possible
using 50 ohm impedence
traces.
Place termination
resistors TX_D0-7,
TX_ER, TX_EN,
GTX_CLK as close to
FPGA as possible
using 50 ohm
impedence traces.
Place 49 ohm termination resistors as
close as possible to G-PHY.
The associated 0.01uF capacitor should
be placed close to the 49 ohm resistors.
