Vitesse Launches Stapleford Integrated 24-port Gigabit Switch IC

4/22/2003 - Vitesse Semiconductor Corp. (Nasdaq: VTSS) announced Stapleford (VSC7303), a 24-port, Gigabit Switch Integrated Circuit (IC) intended to migrate existing 24- and 48-port, 10/100 Local Area Networking (LAN) switch boxes to triple speed Gigabit capabilities. This product is available today for production orders.

Offering wire speed performance and the ability to forward packets at 36 Million/second, this Gigabit Switch-on-Chip combines the highest level of integration and functionality in its class and simultaneously achieves a very low system cost point. Stapleford supports Jumbo packets and provides for wire speed automatic learning. Its Layer 4-aware programmable classifier allows for enhanced Quality of Service, and it is optimized with Reduced Gigabit Media Independent Interface (RGMII) and Reduced Ten Bit Interface (RTBI) to simplify board layout and condense design time. Stapleford also supports Half Duplex Back Pressure and both Multicast and Broadcast Storm Control. This 24-port Gigabit Switch IC dissipates the industry's lowest amount of power, less than five watts, which eliminates the need for external cooling elements and reduces the cost of the power supply unit.

"Vitesse has been successful in leveraging its dominant position in the WAN market into the LAN," said Kevan Smith, business unit director of Vitesse's Ethernet Products Division. "By introducing the next-generation of highly integrated, cost optimized Gigabit Switch ICs, Vitesse is enabling OEMs to aggressively replace the existing Fast Ethernet switches and take advantage of price points two-times that of Fast Ethernet prices as well as the improved performance."

Vitesse's LondonTM Family of Gigabit Switch ICs
Stapleford is a member of the London family of Ethernet switches. London products are designed to yield Gigabit wire-speed performance at extremely competitive prices. All members of the family have a common architecture to ensure ease-of-use and the reusability of software (from 8- to 48 ports). The family offers high levels of integration including optimized on-chip memory and addressing capabilities, which eliminates the need for external memory. Additionally, the London family has multiple controller interfaces allowing OEMs to use a very inexpensive 8051 micro- controller to configure the switch system for unmanaged and Web managed solutions.

Additional Features and Pricing
Stapleford comes with a complete managed reference system solution targeted at the Desktop and Workgroup switch market. The reference platform is optimized with only six-layers of PCB board. This switch is compliant with the following IEEE protocols:

Stapleford is available now. Accompanying this product is a comprehensive library of system hardware and software manuals and other supporting documentation to assist with design and validation. Pricing for volume production is $144 per unit. Stapleford will be running in customer production units during Networld+Interop Las Vegas 2003 taking place April 27-May 2, 2003. Vitesse's booth number is ER-14.
