5.1.5. EMAC Signal Description and Interfaces

The EMAC provides a variety of PHY interfaces and control options through the HPS and the FPGA I/Os.

For designs that are pin-limited on HPS I/O, the EMAC can be configured to expose a GMII interface to the FPGA fabric, which can be routed directly to FPGA I/O pins. Exposing the PHY interface to the FPGA fabric also allows adapting the GMII to other PHY interface types such as RGMII and SGMII using soft logic with the appropriate general purpose, TDS, or transceiver I/O resources.
