Dynamic Switching of 1000BASE-X and SGMII Standards
This chapter provides general guidelines for using the core to perform dynamic standards switching between
Typical Application
Figure 11-1 illustrates a typical application for the Ethernet 1000BASE-X PCS/PMA or SGMII 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 fibre
•The core must operate in SGMII mode to provide BASE-T functionality and use the twisted copper pair.
The GMII of the Ethernet 1000BASE-X PCS/PMA or SGMII core is shown connected to an embedded Ethernet Media Access Controller (MAC), for example the Tri-Mode Ethernet MAC core from Xilinx.
