Gigabit Ethernet MAC with IEEE 1588 PTP Support and AVB for Auto

Overview

The Gigabit Ethernet Media Access Controller with IEEE 1588 PTP IP core is compliant to the Ethernet/IEEE 802.3-2008 standard and has hardware based support for for IEEE 1588 V1 and V2. It performs accurate hardware based timestamping of PTP packets. The Gigabit Ethernet - AHB IP Core provides a 10/100 Mbps Media Independent Interface (MII), a 1000 Mbps Gigabit Media Independent Interface (GMII), and an AHB master/slave interface. The Gigabit Ethernet IP Core is designed for SoC and mobile applications such as integrated networking devices, PCI-Express Ethernet controllers, and Ethernet adapter cards.
