SGMII Interface Electrical Characteristics
Each SGMII port features a 4-wire AC-coupled serial link from the dedicated SerDes 2 interface of
MPC8544E as shown in Figure 7, where CTX is the external (on board) AC-coupled capacitor. Each output
pin of the SerDes transmitter differential pair features 50-
Ω output impedance. Each input of the SerDes
receiver differential pair features 50-
Ω on-die termination to SGND_SRDS2 (xcorevss). The reference
circuit of the SerDes transmitter and receiver is shown in Figure 7.
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 21.5, “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 eTSEC EC_GTX_CLK125 clock is not required for this port. Instead,
SerDes reference clock is required on SD2_REF_CLK and SD2_REF_CLK pins.
8.3.1
AC Requirements for SGMII SD2_REF_CLK and SD2_REF_CLK
Table 23 lists the SGMII SerDes reference clock AC requirements. Please note that SD2_REF_CLK and
SD2_REF_CLK are not intended to be used with, and should not be clocked by, a spread spectrum clock
source.
