    Switched, Fast, and Gigabit Ethernet - CH 3 - Ethernet, Fast Ethernet, and Gigabit Ethern.. Page 1 of 36 [Figures are not included in this sample chapter] Switched, Fast, and Gigabit Ethernet - 3 - Ethernet, Fast Ethernet, and Gigabit Ethernet Standards This chapter discusses the theory and standards of the three versions of Ethernet around today: regular 10Mbps Ethernet, 100Mbps Fast Ethernet, and 1000Mbps Gigabit Ethernet. The goal of this chapter is to educate you as a LAN manager or IT professional about essential differences between shared 10Mbps Ethernet and these newer technologies. This chapter focuses on aspects of Fast Ethernet and Gigabit Ethernet that are relevant to you and doesn’t get into too much technical detail. Read this chapter and the following two (Chapter 4, "Layer 2 Ethernet Switching," and Chapter 5, "VLANs and Layer 3 Switching") together. This chapter focuses on the different Ethernet MAC and PHY standards, as well as repeaters, also known as hubs. Chapter 4 examines Ethernet bridging, also known as Layer 2 switching. Chapter 5 discusses VLANs, some basics of routing, and Layer 3 switching. These three chapters serve as a precursor to the second half of this book, namely the hands-on implementation in Chapters 8 through 12. After you understand the key differences between yesterday’s shared Ethernet and today’s Switched, Fast, and Gigabit Ethernet, evaluating products and building a network with these products should be relatively straightforward. The chapter is split into seven sections: l "Ethernet and the OSI Reference Model" discusses the OSI Reference Model and how Ethernet relates to the physical (PHY) and Media Access Control (MAC) layers of the OSI model.

    Latticesc/M Broadcom XAUI/Higig 10 Gbps Lattice Semiconductor Physical Layer Interoperability Over CX-4

    LatticeSC/M Broadcom® XAUI/HiGig™ 10 Gbps Physical Layer Interoperability Over CX-4 August 2007 Technical Note TN1155 Introduction This technical note describes a physical layer 10-Gigabit Ethernet and HiGig (10 Gbps) interoperability test between a LatticeSC/M device and the Broadcom BCM56800 network switch. The test was limited to the physical layer (up to XGMII) of the 10-Gigabit Ethernet protocol stack. Specifically, the document discusses the following topics: • Overview of LatticeSC™ and LatticeSCM™ devices and Broadcom BCM56800 network switch • Physical layer interoperability setup and results Two significant aspects of the interoperability test need to be highlighted: • The BCM56800 uses a CX-4 HiGig port, whereas the LatticeSC Communications Platform Evaluation Board provides an SMA connector. A CX-4 to SMA conversion board was used as a physical medium interface to cre- ate a physical link between both boards. The SMA side of the CX-4 to SMA conversion board has four differential TX/RX channels (10 Gbps bandwidth total). All four SMA channels (Quad 360) were connected to the LatticeSC side. • The physical layer interoperability ran at a 10-Gbps data rate (12.5-Gbps aggregated rate). XAUI Interoperability XAUI is a high-speed interconnect that offers reduced pin count and the ability to drive up to 20” of PCB trace on standard FR-4 material. In order to connect a 10-Gigabit Ethernet MAC to an off-chip PHY device, an XGMII inter- face is used. The XGMII is a low-speed parallel interface for short range (approximately 2”) interconnects. XAUI interoperability is based on the 10-Gigabit Ethernet standard (IEEE Standard 802.3ae-2002).

    Implementing 10 Gigabit Ethernet XAUI in Stratix GX Devices November 2002, ver. 1.0 Application Note 249 Introduction A main system bottleneck in high-speed communications equipment is data transmission from chip-to-chip and over backplanes. StratixTM GX devices help remedy the problem by supporting 3.125-gigabit per second (Gbps) channels and integrating advanced functionality into the device’s logic array. Versatile Stratix GX transceiver blocks support many emerging industry protocols that require high-speed differential I/O with clock data recovery (CDR) (e.g., 10 Gigabit Ethernet via the 10-Gbps attachment unit interface [XAUI]), SONET scrambled backplane, and custom implementations. The Stratix GX transceiver block is designed to support XAUI. In addition, the other 10 Gigabit Ethernet interface protocols (i.e., 10-gigabit, 16-bit interface [XSBI] and 10-gigabit medium independent interface [XGMII]) are also supported by Stratix GX devices. This application note discusses the following topics: ■ Fundamentals of 10 Gigabit Ethernet & XAUI ■ XAUI electrical specifications ■ Implementing XAUI in Stratix GX devices ■ Using Quartus II to implement XAUI ■ Applications of Stratix GX and XAUI Fundamentals Over the years, Ethernet speed has leapfrogged from the initial 10 megabits per second (Mbps), to 100 Mbps, and more recently to of 10 Gigabit 1 Gbps. Today, the Ethernet is the dominant network technology in local Ethernet & area networks (LANs), and with the advent of the 10 Gigabit Ethernet, it is now competitive in the metropolitan area network (MAN) and wide XAUI area network (WAN) markets. The purpose of the 10 Gigabit Ethernet standard is to extend IEEE 802.3 (Ethernet) operating speed to 10 Gbps and include WAN applications.
