Fast Ethernet 10/100 802.3 MAC with IEEE 1588 PTP Support

Overview

The Arasan 10/100 Ethernet Media Access Controller with IEEE 1588 support IP core is compliant to the Ethernet/IEEE 802.3-2008 standard. It also includes hardware to parse and accurately time-stamp packets to support the IEEE 1588 PTP protocol. The 10/100 Ethernet - AHB IP core provides a 10/100 Mbps Media Independent Interface (MII), an optional RMII interface, and an AHB master/slave interface. The IP core is designed for SoC and mobile applications such as integrated networking devices, PCI-Express Ethernet controllers,and Ethernet adapter cards
