1 Introduction

Product Overview 1.1

The LAN24225 and LAN34225 are server grade, dual Gigabit Ethernet Modules. They provide two Small Form-factor Pluggable (SFP)
connectors that will accept a pre-installed multi-mode Fiber SFP module, or a customer supplied SFP module. This allows the flexibility to have
any combination of multi-mode fiber, single-mode fiber, or twisted pair interfaces. A PCIe x4 interface ensures excellent bandwidth for
communication with the CPU.

Board Features 1.2

The following sections describe the major features of the LAN24225 FireWire communication module.

 General Features

o PCIe x4 Connection

 PCIe/104 or PC/104-Express Type 2 connection

o Two Independent Gigabit Ethernet Connections

 1000 Mbps SFP on each channel
 Does not support 10/100 Mbps
 Full Duplex support

o Chipset

 Intel 82575EB PCIe Gigabit Ethernet Controller
 Pre-boot eXecution Environment (PXE) enables system to boot up via the LAN

o Gigabit MAC/PHY Advanced Features

 Intel® I/O Acceleration Technology (Intel® I/OAT) accelerates TCP I/O for improved CPU utilization.
 MSI-X support minimizes the overhead of interrupts and allows load balancing of interrupt handling between

cores/CPUs.

 Mechanism available for reducing interrupts generated from Tx/Rx operations to maximize system

performance and throughput.

 Dual 8 kB configurable Rx and Tx FIFO buffers means no external FIFO memory requirements.
 Support for transmission and reception of jumbo frames up to 9.5kBytes enables higher and better throughput

of data.

 IEEE 802.3 compliant flow-control support with software-controllable pause times and threshold values to

reduce frame loss from receive overruns.

o Host Offloading Features

 Direct Cache Access (DCA) enables the I/O device to activate a pre-fetch engine in the CPU that loads the

data into the CPU cache before use, eliminating cache misses and reducing CPU load.

 Checksum offloading, segmentation offloading, and packet filtering capabilities lower processor utilization.
 IEEE 802.1q virtual local area network (VLAN) support with VLAN tag insertion, stripping and packet filtering

for up to 4096 VLAN tags allows creation of multiple VLAN segments.

o Multi-Mode SFP (with -1 option)

 Avago AFBR-5715APZ or equivalent
 850nm
 For use with Multi-Mode Fiber Optics
 LC Connector
 Bail latch

 Software

o Supports Windows 7/XP (included on companion CD)

 Windows 7 requires Intel driver, not pre-packaged Microsoft driver

o Open source Linux drivers included in the kernel
o Drivers included in most modern operating systems. Check with the OS manufacturer

Ordering Information 1.3

The LAN24225 is available with the following options:

Throughout this document, LAN24225 refers to both the LAN24225 and LAN34225 unless otherwise noted.

The Intelligent Data Acquisition Node (IDAN™) building block can be used in just about any combination with other IDAN building blocks to
create a simple but rugged 104™ stack. This module can also be incorporated in a custom-built RTD HiDAN™ or HiDANplus High Reliability

Intelligent Data Acquisition Node. Contact RTD sales for more information on our high reliability systems.
