This section provides general guidelines for creating SGMII designs, and designs capable of switching between 1000BASE-X and SGMII standards (Dynamic Switching), using a device-specific transceiver. Throughout this section, any reference to SGMII also applies to the Dynamic Switching implementation. Dynamic Switching between 2500BASE-X and 2.5 G SGMII is not supported by the core.
For information about the SGMII example design see SGMII/Dynamic Switching Using a Transceiver Example Design.
