The Lattice Semiconductor 25G Ethernet (GbE) IP core supports the ability to transmit and receive data between a host processor and an Ethernet network. The 25GbE IP core consists of the 25-Gigabit Media Independent Interface (25GMII), which connects media access controllers (MACs) and Physical Layer devices (PHYs).
This IP Core is supported in the Lattice Avant-X FPGA for all available PCS and MAC options. These options are available in the Lattice Radiant™ software.
Resource Utilization details are available in the IP Core User Guide.
