Vitesse Delivers Industry's First QUADSpeed MAC

2/25/2003 - Vitesse Semiconductor Corporation (Nasdaq: VTSS) broadened its family of high-performance, multi-purpose Gigabit Ethernet and 10 Gigabit Ethernet Media Access Controllers (MACs) by introducing Meigs-IITM (VSC7321) and LansingTM (VSC7322).

Both devices provide system OEMs a flexible, low cost, low power 10Gbps MAC solution with an integrated industry standard host interface for seamless scaling of Ethernet line card designs. These MAC devices are ideal for current and next-generation Enterprise and Metro applications such as L2/3 Ethernet Switches, Edge Routers, Add/Drop Multiplexers (ADM) deploying Ethernet-over-SONET/SDH, Multi-service Provisioning Platforms, and Content Switches.

Meigs-II, the industry's first QUADSpeed MAC, combines ten triple-speed (10/100/1000 Mbps) ports, a single 10GbE port, and an OIF-compliant SPI-4.2 System Interface to form the industry's highest density 10Gbps MAC. Meigs-II is Vitesse's second generation MAC solution and is designed for use in modular Ethernet Switch platforms as well as emerging Ethernet-over-SONET/SDH (EoS) applications when used in conjunction with the Vitesse VSC9118. The VSC9118 is the industry's highest density, OC-192 channelized, multi-service mapper supporting both frame-based and transparent-based GFP. Together, Meigs-II and VSC9118 provide five times the port density over currently available products, thereby reducing the deployment cost of Ethernet services in Metro networks.

The extensive per port buffering capability of Meigs-II enables loss-less flow control in Metro networks, thus preventing packet loss due to a client exceeding their provisioned service level. The individual per port shaping mechanisms allow service providers to not only offer a loss-less environment, but also to manage the provisioning level in increments as fine as 256 kbps. This will permit OEMs to offer more stringent and dynamic service provisioning level not traditionally found in Ethernet networks.

The 10/100/1000 ports, on the Meigs-II, interface to a variety of physical layer copper devices using either the MII or GMII interfaces. The integrated GbE serializer/deserializer (SERDES) interfaces enable high density, cost-efficient per port pricing for optical Ethernet applications. The integrated 10 Gigabit Attachment Unit Interface (XAUI) seamlessly connects to 10Gbps module Multi-Sources Agreements (MSA) such as XENPAK, X2, and XPAK as well as facilitating a solution for ultra-small form factor MSAs such as the XFP. On the System Interface side, the Meigs-II incorporates the industry standard OIF SPI-4.2 interface for seamless connection to devices such as network processors and OC-48/192 mappers.

"OEMs are continuously confronted with the cost, density, and connectivity cycle. By offering the industry's first QUADSpeed MAC device, with an integrated SPI-4.2 System Interface, Vitesse simplifies the design of high density, triple-speed Ethernet or 10 Gigabit Ethernet solutions by employing a common 10Gbps Ethernet MAC architecture," said Mark Fauber, product marketing manager for Vitesse's Ethernet Products Division. "Meigs-II provides system OEMs a versatile, standard's compliant, 10Gbps MAC solution for scaling their Ethernet line card designs for rapid time-to-market."

Meigs-II, which operates over the extended temperature range of 0C to +85C, is available in a 728-pin TBGA package and is priced at $280 in quantities of 1000. Samples are available now with production quantities available in May 2003.

The other addition to Vitesse's GbE MAC family, Lansing, integrates 10 triple-speed ports supporting either RGMII for copper PHY connections or RTBI for connection to an external SERDES. Lansing, which is designed for use in modular Ethernet Switch platforms, also incorporates a CSIX-compliant 64-bit interface, a serial CPU interface, and a MII Management interface. This first generation MAC device has successfully completed both Fast Ethernet and Gigabit Ethernet testing at the University of New Hampshire's InterOperability Lab.

Lansing comes in a 680-pin TSBGA package and is now available in production quantities. It is priced at $250 per unit in quantities of 1000.

"The availability of highly integrated and multi-function Ethernet chipsets will continue to drive the migration of Gigabit Ethernet and 10 Gigabit Ethernet speeds into enterprise LAN infrastructure and emerging service provider MAN infrastructure designs," said Sean Lavey, an analyst with IDC.
