Networking Silicon — GD82559ER

2.310/100 Mbps Serial CSMA/CD Unit Overview

The CSMA/CD unit of the 82559ER allows it to be connected to either a 10 or 100 Mbps Ethernet network. The CSMA/CD unit performs all of the functions of the 802.3 protocol such as frame formatting, frame stripping, collision handling, deferral to link traffic, etc. The CSMA/CD unit can also be placed in a full-duplex mode, which allows simultaneous transmission and reception of frames.

2.410/100 Mbps Physical Layer Unit

The Physical Layer (PHY) unit of the 82559ER allows connection to either a 10 or 100 Mbps Ethernet network. The PHY unit supports Auto-Negotiation for 100BASE-TX Full Duplex, 100BASE-TX Half Duplex, 10BASE-T Full Duplex, and 10BASE-T Half Duplex. It also supports three LED pins to indicate link status, network activity, and speed.The 82559ER does not support external PHY devices and does not expose its internal MII bus.
