SGMII Clock Differential Output Pair (used in SGMII to CAT5/SerDes/AMS PHY Oper-
ating Modes).
This signal pair is a differential 625MHz SGMII clock for the SGMII data in accordance
with Cisco’s SGMII specification. These pins should be AC-coupled with external 0.01μF
series capacitors or left unconnected when not used. See

Fiber Transceiver Differential Input Pair (used in SGMII to SerDes PHY Operating
Modes).
Differential 1.25Gbaud receiver inputs with register selectable on-chip 100Ω or 150Ω dif-
ferential termination. The SDIP and SDIN signals should be AC-coupled with external
0.01μF series capacitors. These signals usually connect to the RX signals of the Fiber
Optic Transceiver or the RX signals of a SerDes over the Backplane.
Fiber Transceiver Differential Output Pairs (used in SGMII to SerDes PHY Operating
Modes).
Differential 1.25Gbaud transmitter outputs. The SDOP and SDON signals should be AC-
coupled with external 0.01μF AC series capacitors, placed on the PHY side of these
traces. These signals usually connect to the TX signals of the Fiber Optic Transceiver or
the TX signals of a SerDes over the Backplane. The register selectable 100Ω or 150Ω dif-
ferential termination should be placed near the Transceiver/SerDes. For information about
adjusting the output swing of these pins, see
