Adapter and Controller Overview

Adapters based on an Intel
TX (100 Mbps operation) and 10BASE-T (10 Mbps operation).
Adapter Block Diagram
The main components of Intel Fast Ethernet adapters are:
The adapters are based on 100BASE-TX specifications. 100BASE-TX is a specific scheme
designed for use over 2 pairs of Category 5 unshielded twisted-pair cable. 100BASE-TX defines a
signaling scheme for 100 Mbps and provides compatibility with the existing 10 Mbps IEEE 802.3
10BASE-T signaling standard. Since only 2-wire pairs are used, TX technology allows full duplex
operation at 100 Mbps. The Intel 82555 is one possible TX solution.
The block diagram below illustrates an Intel
MAC with a TX or T4 PHY.

A Fast Ethernet Media Access Controller (MAC), such as the 8255x, is the core component.
The MAC supports the Fast Ethernet ANSI/IEEE 802.3u standard.
A Physical Layer (PHY) interface device is also required. The 82558, 82559, 82550, and
82551 components have an integrated PHY that supports 100BASE-TX and 10BASE-T.
Adapters based on the 82557 must include an appropriate PHY component for their design.
A serial EEPROM is required to hold the adapter’s individual Ethernet node address and other
configuration information including fixed PCI configuration parameters.
