Low-Latency EMAC, 10G and 25G

lowlatency block lowlatency block

Very short MAC latency with lean logic for 10G and 25G Ethernet.

The Low-Latency EMAC focuses on minimal Tx and Rx pipeline depth and integrates cleanly with UDP and TCP offload engines. It is available for 10G and for 25G variants that include PCS and RS-FEC when required.

Highlights

  • Very short MAC latency at 10G with documented Tx and Rx figures
  • 25G option that integrates EMAC, PCS, and RS-FEC for robust links
  • AXI-Stream or FIFO user interfaces that align with UDP and TCP cores
  • Reference designs and loopback methods for accurate measurement

Why Macnica?

    • MAC selection and transceiver planning for specific Agilex boards and mezzanines
    • End-to-end latency budgeting that includes PHY, MAC, offload core, and user logic
    • Golden tests for loopback, PRBS, and packet timing that your team can repeat
    • Guidance for cabling, optics, and RS-FEC choices to meet link budget and reliability goals
    • Production support for version control and test plans that keep your latency numbers stable across builds
