The Triple-Speed Ethernet Intel® FPGA IP core consists of a 10/100/1000 Mbps Ethernet media access control (MAC) and physical coding sublayer (PCS) Intellectual Property (IP). This IP function enables Intel® FPGAs to interface to an external Ethernet PHY device, which interfaces to the Ethernet network.
This IP is offered in MAC-only mode or in MAC+PHY mode. In the MAC only mode, the IP uses an external PHY chip to do signaling. The two supported interfaces to the external PHYs are: GMII (8-bit interface at 125 MHz SDR) and RGMII (4-bit interface at 125 MHz DDR).
In the MAC+PHY mode, the PHY is realized using on-chip transceivers or LVDS I/O with dynamic phase alignment (DPA) logic that can operate up to 1.25 Gbps. SGMII or 1000Base-X protocol is used in this case. The usage of LVDS I/Os enables very scalable multiport gigabit Ethernet (GbE) system designs while saving the serial transceivers for higher performance protocols.
