This Figure illustrates a typical application for the QSGMII core when operating in PHY mode, using a device-specific transceiver to provide the serial interface.
• The device-specific transceiver is connected to an external off-the-shelf Ethernet MAC device that also supports QSGMII. (This can be multiple instances of tri-mode MAC providing 10/100/1000 Mbps operation, for example, the Xilinx Tri-Mode Ethernet MAC core connected to QSGMII core in MAC mode.)
• The GMII/MII interface of QSGMII core is connected to a tri-mode PHY providing 10BASE-T, 100BASE-T, and 1000BASE-T operation.
