A Vitesse Switch Family Member

SparX-G16r is a part of the Vitesse SparX™ Family of Unmanaged or

Web-Managed Switches and takes the family into a new generation of

integration. With its 8 tri-speed Gigabit Ethernet copper ports and 8 SGMII

ports, it is specifically targeted at SMB, SME, and SOHO unmanaged

applications, and with its on-chip V-Core CPU and parallel CPU interface,

it enables web-managed and managed switch applications.

Being a member of the SparX™ switch family provides a number of unique

advantages when designing with the device, including software

compatibility between members. Software written for SparX-G16r can

therefore easily be ported from or used with other switch configurations in

the family, and vice-versa.

Additionally, building a product family is easy when designing with Vitesse

switches. Upgrading designs to higher port counts, or migrating to other

configurations or future technology is achievable with a minimum of effort

and time.

The Vitesse SparX Family Of Switches

SparX-G16r, as part of the Vitesse SparX Family of Switches, shares the

unique traits of the family. The highly integrated switches require no

external memory, and the integration of copper PHY as well as internal

oscillator circuits simplifies the design effort. The requirement of needing

only 2 power supply rails reduces the additional DC/DC converter cost.

Further trimming down system cost is the

persistently low power dissipation of the family.

In addition, the value-added features in

SparX-G16r enables the customer to provide

advanced features without the need of

enterprise class silicon.

The switches provide non-blocking, wire-speed performance designs with

wire-speed MAC address learning or CPU-based address learning.

Designing both unmanaged and managed solutions is straight-forward.

The devices offer both an internal V-Core CPU and 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.

Controlling networks operated by the Vitesse switches is simple; advanced

classification with IPv4 and IPv6 support, along with port DSCP remarking

and 802.1x authentication support, provide flexible QoS operation. This is

backed up by Layer 2–4 link aggregation and VLAN support, enabling

managed switches to be deployed.

With its unique low power dissipation, SparX-G16r reduces thermal

management cost for system design and thereby provides for higher

system reliability to the benefit of the user.

Designing with Vitesse SparX Family of Switches means designing with

the whole Vitesse Solution. The outstanding Vitesse web-managed switch

software system that runs on the on-chip V-Core CPU is provided. This is

in addition to the unmanaged and smart managed software systems for an

external 8051, which are also included. For homegrown software

development, our full platform and OS independent switch API is supplied.

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 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.

VSC7391 SparX-G16r™ is the highly integrated, single-

chip Gigabit Ethernet switch with 8 Integrated GbE Copper

PHY ports. As part of the Vitesse SparX™Family of

Switches, SparX-G16r delivers high performance with

easy migration paths, and comprehensive system

solutions that enable ultra-short time-to-market and

market-leading system cost.
