C1/2/3 = 4.7 µF
L1/2 = 1 µH
R1/2 = Depends on SerDes chip used
R3/4 = Depends on SerDes chip used
R7/8 = Biasing (depends on SerDes chip)
Place R1/2/3/4/7/8 close to SerDes chip
Place R5/6 close to Infineon transceiver
Figure 7
Values of R1/2/3/4 may vary as long as proper 50 Ω termination to V_EE or 100 Ω
differential is provided. The power supply filtering is required for good EMI performance.
Use short tracks from the inductor L1/L2 to the module V_CCRx/V_CCTx.
