Ethernet: Enhanced Three-Speed Ethernet (eTSEC)
This section provides the AC and DC electrical characteristics for the enhanced three-speed Ethernet
controller.
8.1
SGMII Interface Electrical Characteristics
Each SGMII port features a 4-wire AC-coupled serial link from the dedicated SerDes1 interface of the
MPC8378E 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_SRDSn (xcorevss). The reference
circuit of the SerDes transmitter and receiver is shown in Figure 65.
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. Also, when operating in SGMII mode, the eTSEC EC_GTX_CLK125
clock is not required for this port. Instead, the SerDes reference clock is required on L1_SD_REF_CLK
and L1_SD_REF_CLK pins.
