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 a standalone 25G Ethernet PCS IP, standalone 25G Ethernet MAC IP, or a combined 25G PCS & MAC following the IEEE 802.3 25G BASE-R specification.

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.

IEEE 802.3 25G BASE-R PCS/PMA Functions – Supports standard 25 Gbps Ethernet link layer data rate

Features

  • PCS: 64b/66b encoding and decoding
