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

Overview

The 10 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.
