Features

One MAC, every media.

Media

Pluggable adapters

MII / GMII / RGMII / SGMII interfaces plus digital 1000BASE-X PCS — one core, swappable media.

Flow control

802.3x PAUSE

Standards PAUSE flow control, with an optional PFC hook for lossless classes.

Delivery

Config-driven IP

A unified, parameterized core — synthesizable RTL, independently verified, customer-owned.
