Typical Magnetics For Gigabit Lan Controller With Optional Resistors Footprint - Intel 82541PI Design Manual

82541PI(ER) and 82562GZ(GX) Dual Footprint LOM Design Guide
3. Replace the magnetics for the 82541PI(ER) with the one for the 82562GZ(GX) and then
populate R1/R2 and R3/R4 for an 82562GZ(GX) LOM design. Refer to
TDCT
Where Rw may be any value between 0-ohms and 100-
R1, R2, R3, and R4 are not populated for 1000Base-T
