Stapleford™ - 24-port Gigabit Ethernet Switch-on-a-Chip
GENERAL DESCRIPTION:
Stapleford™ is a highly integrated, singlechip Ethernet switch with 24 non-blocking
ports. High performance with easy migration
paths and comprehensive System Solutions
enableing ultra-short time-to-market and
market leading system cost.
A Vitesse Switch Family Member
Stapleford is a part of the Vitesse London Family Of Switches.
With its high port density of 24 tri-speed ports, it is specifically
targeted at desktop and medium business applications.
Being a member of the switch family provides a number of
unique advantages when designing with the chip, including
nearly 100% software compatibility between members. Thus,
software written for Stapleford can easily be used with other
switch configurations in the family, and vice-versa.
Designing both unmanaged and managed solutions is
straightforward. The chips offer both serial and parallel CPU
interfaces, and support a host of management protocols such as
GxRP, SNMP, and three flavors of Spanning Tree: Standard STP,
Multiple STP, and Rapid STP.
Gaining control with networks operated by the Vitesse switches is
simple; advanced Layer 2-4 classification, plus shaping and
policing functionality, along with port authentication support,
provide flexible QoS operation. This is backed up by link
aggregation and VLAN support, enabling advanced techniques
such as “802.1Q-in-802.1Q” to be deployed. Additionally, OAM is
supported for designing switch products for Ethernet in the MAN.
Designing with Vitesse London Family Of Switches means
designing with the whole Vitesse Solution:
Additionally, building a product family is easy when designing
with Vitesse switches. Migrating designs to other port counts
or other configurations, or to future technology, is achievable
with minimum effort and time.
The outstanding Vitesse web managed switch software system
that runs on a standard 8051 controller, is provided. This is in
addition to the unmanaged and smart managed software systems
for 8051, which are also included. For homegrown software
development our full switch API is supplied.
The Vitesse London Switch Family
Stapleford, as part of the Vitesse London Family Of Switches,
shares the unique traits of the family.
Accompanying the software systems are the Vitesse Switch
Reference Systems. These are production-ready hardware
designs that also serve as evaluation platforms for our switches.
The highly integrated switches require no external memory at
all, and the use of Reduced Mode interfaces (RGMII and
RTBI) simplifies PCB layout to reduce time and cost. Further
trimming down system cost is the persistently low power
dissipation of the family.
The Vitesse Solution is supplied with a comprehensive collateral
package, which includes software source code, full documentation,
and an in-depth qualification report for easy pre-evaluation.
