10Gb Ethernet MAC+PHY IP Core

Ethernet Transmission of Data Frame Compliant to the IEEE 802.3-2012 Standard

The Lattice Semiconductor 10G Ethernet (GbE) IP core supports the ability to transmit and receive data between a host processor and an Ethernet network. The 10GbE IP core consists of the 10-Gigabit Media Independent Interface (XGMII), which connects media access controllers (MACs) and Physical Layer devices (PHYs).

This IP Core is supported in the Lattice Avant™-G, Lattice Avant™-X FPGA for both the MAC, PHY and MAC & PHY combos. For CertusPro™-NX device family, the MAC, PHY and MAC + PHY + 1588 options are available. These options are available in the Lattice Radiant™ software.

Resource Utilization details are available in the IP Core User Guide.

Features

  • Supports standard 10 Gbps Ethernet link layer data rate
  • 64-bit wide internal datapath operating at 156.25 MHz
  • AXI4-Stream interface on the client’s transmit and receive interfaces

PHY

  • Designed to the IEEE 802.3-2012 10GBASE-R specification
  • 64b/66b encoding and decoding
  • XGMII interface: 64-bit, 156.25 MHz
  • Supports AXI4-Lite and management data input/output (MDIO) interfaces for PCS/PMA and MDIO manageable device (MMD) register access

MAC + PHY + 1588 (CertusPro™-NX)

  • Supported APB register access
  • Timestamping support as specified in the IEEE 1588v2 (2-step mode)
