Family of Products for Next Generation Networks Provide the

Performance and Intelligence Needed to Transport Voice, Video, and

Data Services Over LANs, MANs and WANs

Broadcom Corporation (Nasdaq:BRCM), the leading developer of integrated circuits enabling broadband communications, today presented at Networld+InterOp an overview of its broad suite of silicon products to drive next-generation converged voice, video, and data IP network services over local, metropolitan and wide area networks at speeds ranging from 100 million bits per second to 10 billion bits per second.

As Internet traffic increases due to new applications, such as Voice over Internet Protocol (VoIP) and streaming video, Broadcom's extensive portfolio of advanced transceiver, framer, switching, media access controller (MAC), network security, network processor and System I/O(TM) silicon technology will provide the intelligence, Quality of Service (QoS), and performance needed for the economic build out of tomorrow's networks.

Broadcom is the first semiconductor supplier to offer a complete line of all-CMOS, multi-protocol chips for 1-, 2.5- and 10-Gigabit network equipment that spans from the desktop to the WAN. Use of CMOS process technology enables higher levels of integration, reduced power consumption, reduced component count and smaller system-level product footprints, thereby reducing the cost of developing 1-Gigabit Ethernet (GbE), 10-GbE, OC-48 (2.5 Gigabits per second/Gbps) and OC-192 (10 Gbps) equipment.

Based on its combination of recently announced products, Broadcom expects to accelerate GbE adoption to the desktop in corporate enterprise LANs. Broadcom's chips will also enable the economical build out of 1 and 10 GbE in MANs with seamless interfaces to the synchronous optical networks (SONET) transport network, and will significantly increase the densities and economies of scale of transport networks based on 10 GbE and OC-192 Synchronous Optical Network (SONET).

"The solutions we've described today demonstrate how the fruits of our acquisition strategy are paying off," said Dr. Henry Samueli, Broadcom's Co-Founder and Chief Technical Officer. "Technology from recent acquisitions including Allayer Communications, BlueSteel Networks, Newport Communications, ServerWorks and SiByte, has been incorporated into our end-to-end solutions."

"Today's LANs, MANs, and WANs operate at different speeds, use different protocols, and lack synergy and overall cost and performance optimization," continued Samueli. "With our comprehensive CMOS silicon solutions for 1 and 10-Gigabit Ethernet, OC-48 and OC-192 SONET, Broadcom is uniquely positioned to enable manufacturers to quickly develop affordable solutions that meet their power, cost, and performance objectives while integrating the intelligence required in the next-generation of converged IP networks."

In the enterprise and access network, Gigabit Ethernet boosts data transmission up to ten times the speed of 10/100 Ethernet and provides the bandwidth needed to support the explosive growth of Internet and enterprise network traffic between service providers, servers, workstations and desktop computers. At the next level, 1 and 10 GbE are the technologies that will provide reliable, cost-effective, high-performance networking capability for metro access switches, routers and line cards for multi-service provisioning platforms. These networks will benefit from the maturity and cost effectiveness of Ethernet protocol equipment. 10 Gigabit Ethernet is a natural choice for the MAN because it matches the installed WAN backbone speed of OC-192 optical fiber networks.

According to the Gartner Group, the market for Gigabit Ethernet is expected to increase from 3.9 million switch ports in 2000 to 38 million switch ports in 2004. During the same period, the number of 10-Gigabit (OC-192 and 10-GbE) nodes is expected to grow significantly, increasing from 150,000 nodes in 2000 to 5.2 million nodes in 2004.

Gigabit to the Desktop

Broadcom is accelerating the proliferation of Gigabit Ethernet into mainstream network computing by providing the smallest, highest performance and most complete GbE solutions at market enabling price points. Gigabit Ethernet can deliver a ten-fold increase in performance over today's Fast Ethernet to eliminate bottlenecks in enterprise networks caused by increased Internet and business enterprise traffic. With more than two million GbE ports shipped, and a full complement of GbE switching, media access controller, network security and physical layer (PHY) solutions, Broadcom is well-positioned to support the industry's migration to Gigabit Ethernet. Key products in Broadcom's enterprise networking portfolio include:

-- BCM5701 Single-Chip Gigabit Ethernet MAC/PHY for Network Interface Cards
(NICs) and LAN-on-Motherboards (LOMs) for servers, workstations, desktops and
portable PCs.

10-Gigabit Ethernet in MANs

Broadcom offers the first complete end-to-end 10-GbE network silicon solution for intelligent aggregation of local network traffic to MANs and simplified POP scalability for reducing operation costs. By providing complete integrated system solutions for line cards, metro switch and router solutions, and 10-GbE backplane connections with accompanying software and reference designs, Broadcom can significantly reduce system design complexity and reduce time to market for network system manufacturers. Key products in Broadcom's MAN portfolio include:

OC-48 and OC-192 in the WAN

Broadcom is the only company to offer a complete line of 10-Gigabit SONET semiconductor solutions manufactured entirely in CMOS process technology. This process technology allows Broadcom to rapidly develop next-generation highly integrated optical transport silicon solutions that consume 70 percent less power than competitive silicon germanium and gallium arsenide solutions, as well as exceed the latest Telcordia, ANSI and ITU-T specifications for jitter performance. As channel capacity increases in Dense Wavelength Division Multiplexing (DWDM) applications it becomes essential to scale down power consumption in equipment. By reducing the power consumption, Broadcom enables manufacturers to deliver very compact, high port density solutions that maximize network bandwidth in WANs. Key products in Broadcom's optical networking portfolio include:
