LogiCORE IP AXI Ethernet (v3.00a) Data Sheet (AXI) - 3.00a English - This document provides the design specification for the LogiCORE IP AXI Ethernet core. This core implements a tri-mode (10/100/1000 Mb/s) Ethernet MAC or a 10/100 Mb/s Ethernet MAC. It supports the most popular PHY interfaces, including 1000BASE-X and SGMII. The core optionally supports Ethernet AVB (Audio Video Bridging) functions. This core provides a control interface to internal registers via a 32-bit AXI4-Lite Interface subset.optionally supports Ethernet AVB (Audio Video Bridging) functions.
