The core is compliant with clause 36 of the IEEE802.3 standard and implements 8B/10B coding, link synchronization, frame encapsulation generation / termination. The core also supports Auto-Negotiation (clause 37 of IEEE802.3 standard). In addition to standard compliance, the core provides support for proprietary or industry standard 2500Base-X 2.5Gbps, 2000Base-X 2Gbps ethernet connections.
