Section 1: Introduction
The NetXtreme and NetLink family of Media Access Controller (MAC) devices are highly-integrated, single-chip
Gigabit Ethernet LAN controller solutions for high-performance network applications. These devices integrate
the following major functions to provide a single-chip solution for Gigabit LAN-on-motherboard (LOM) and
network interface card (NIC) applications.
• Triple-speed IEEE 802.3-compliant MAC functionality
• Triple-speed IEEE 802.3-compliant Ethernet PHY transceiver
• PCI Express (PCIe) bus interface
• On-chip packet buffer memory
• On-chip RISC processor for custom frame processing
