12.3.2.1. Use Cases

You can only instantiate a maximum of two HPS EMAC instances with the HPS RGMII interface due to the HPS I/Os count restrictions.

Additional EMAC must be exposed to the FPGA fabric as GMII interfaces, which can interface to a soft 1G/2.5G/5G/10G Multirate Ethernet PHY IP, which integrates a full soft PCS as well as transceiver Hard IP SerDes interface (XCVR and LVDS). This can be used to drive 1G (1.25 Gbps) SGMII to an external Ethernet PHY.
