The following figure shows a typical application for the core with the ability to dynamically
switch between 1000BASE-X and SGMII standards.
The FPGA is shown connected to an external, off-the-shelf PHY with the ability to perform both BASE-X and BASE-T standards.
- The core must operate in 1000BASE-X mode to use the optical fiber.
- The core must operate in SGMII mode to provide BASE-T functionality and use the twisted copper pair.
The GMII of the 1G/2.5G Ethernet PCS/PMA or SGMII core is shown connected to an embedded Ethernet Media Access Controller (MAC), for example, the AMD Tri-Mode Ethernet MAC core.
