SGMII Interface Electrical Characteristics
Each SGMII port features a 4-wire AC-coupled serial link from the dedicated SerDes interface of
MPC8313E as shown in Figure 15, where CTX is the external (on board) AC-coupled capacitor. Each
output pin of the SerDes transmitter differential pair features a 50-
output impedance. Each input of the
SerDes receiver differential pair features 50-
on-die termination to XCOREVSS. The reference circuit
of the SerDes transmitter and receiver is shown in Figure 33.
When an eTSEC port is configured to operate in SGMII mode, the parallel interface’s output signals of
this eTSEC port can be left floating. The input signals should be terminated based on the guidelines
described in Section 22.5, “Connection Recommendations,” as long as such termination does not violate
the desired POR configuration requirement on these pins, if applicable.
When operating in SGMII mode, the TSEC_GTX_CLK125 clock is not required for this port. Instead, the
SerDes reference clock is required on SD_REF_CLK and SD_REF_CLK pins.

DC Requirements for SGMII SD_REF_CLK and SD_REF_CLK
The characteristics and DC requirements of the separate SerDes reference clock are described in Section 9,
