Description

The EA-224 provides four 10/100Mbps Ethernet network access interface ports. MII interface is used to connect external PHY devices for 100 Mbps Ethernet. They also can direct connect with standard 10Mbps serial interface.

The EA-224 provides the Ethernet MAC protocols, handles the local buffer memory interface and management, arbitrates among multiple priority queues, and interfaces with the XpressFlow Engine and other Access Controllers through the XpressFlow message passing protocol.
