Broadcom Announces the First 0.13-micron CMOS Multi-Rate Gigabit Octal Serializers/Deserializers

10/30/2002 - Broadcom, the leading provider of integrated circuits enabling broadband communications, announced two new Serializer/Deserializer (SerDes) products - the Broadcom® BCM8020 eight-channel multi-rate transceiver and BCM8040 eight-channel multi-rate retimer/switch.

With current economic conditions forcing equipment designers to reduce product development costs, these new SerDes devices will permit Original Equipment Manufacturers (OEMs) to extend the life of legacy backplanes without jeopardizing performance. The BCM8020 and BCM8040 can increase transmission speed over existing backplanes by 2 times, 4 times, or even up to 8 times, and enable higher capacity and faster system upgrades while preserving the existing installed chassis base. Backplanes provide the main interconnection between the server chassis and the rest of the network.

The BCM8020 and BCM8040 were developed using low power 0.13-micron CMOS process technology, and both are ideal for higher levels of integration into application-specific ICs (ASICs) or switching fabrics where further reductions can be realized in the form of power, space, and cost savings over discrete solutions.

The BCM8020 and BCM8040 provide users with a total usable bandwidth capacity of up to 20 Gigabits per second, offering a high-speed, low-cost alternative to fiber connections. For applications such as stackable switching systems or rack-to-rack interconnections that require larger data transfers over shorter distances, each chip can be used with low-cost, highly reliable copper cables. Broadcom has demonstrated 10- Gigabit bi-directional, error-free operation, supporting distances over 15 meters in length using the Infiniband 4X cable.

"We have worked closely with Broadcom on key SerDes technology that helps enable our next generation platforms," said Karl Triebes, Vice President of Hardware Engineering for Foundry Networks. "These latest SerDes products from Broadcom continue to support our end-to-end network infrastructure solutions and provide the price and performance objectives that we require."

Building on Broadcom's current leadership in SerDes technology, the BCM8020 and BCM8040 provide exceptional jitter performance that exceeds both the IEEE 802.3ae and GR-253 specifications supporting Ethernet and SONET-based networking equipment. The patented SerDes architecture supports data rates ranging from 1.0 Gigabit to 3.2 Gigabits and can be synthesized from the on-chip phase lock loop (PLL). In addition, the BCM8020 and BCM8040 features pre-emphasis and equalization of bandwidth limited-channels to provide network equipment designers with highly robust, flexible solutions for high-speed copper links.

Peter Traver, GbX Project Manager at Teradyne, Inc. said, "When combined with Teradyne's high-speed, high-density GbXTM connectors, Broadcom's new 0.13-micron CMOS products provide a low-power, high-performance solution that greatly reduces bandwidth bottlenecks across backplane environments."

The BCM8020 integrates eight independent transceiver channels and has two complete IEEE 802.3ae 10-Gigabit Ethernet Physical Coding Sublayers (PCS) with selectable 8B/10B encoding/decoding on-chip. As a result, the device can be configured to support two independent 10-Gigabit Attachment Unit Interfaces (XAUI) with 10-Gigabit Media Independent Interface (XGMII) SerDes channels. The device can also support the Ten Bit Interface (TBI) or Reduced Ten Bit Interface (RTBI) low-speed interfaces.

The BCM8040 integrates sixteen independent transceivers supplying eight complete retiming channels with two full IEEE 802.3ae 10-Gigabit Ethernet PCS blocks on-chip. It can be configured to support two independent XAUI to XAUI retiming channels, a single XAUI to dual XAUI switch, or as a single XAUI to three XAUI switch for applications requiring redundant interfaces.

"These 0.13-micron CMOS chips extend Broadcom's leadership in high-speed SerDes technology," said Robert A. Rango, Vice President and General Manager of Broadcom's Network Infrastructure Business Unit. "Our latest designs will support customers who need standard SerDes products as well as customers who want to integrate these SerDes devices with their own proprietary IP into larger CMOS products such as switches or application-specific ICs."

The BCM8020 and BCM8040 complement three generations of Broadcom SerDes cores available in high production volumes today. Higher layer function devices, such as Broadcom's StrataXGSTM family of switching products, leverage this technology and integrate up to 32 high-speed 3.125 Gigabit SerDes and over 10 million logic gates in a single chip. Broadcom also designs and manufactures ASICs that utilize as many as 36 high-speed 3.125 Gigabit SerDes with over three million logic gates and memory in a single chip. Broadcom's SerDes products and cores are widely used throughout the industry, reinforcing its market leadership in SerDes technology.

The BCM8020 and the BCM8040 are sampling today with production quantities expected in early 2003.
