VSC7398
SparX-G8eTM-Enhanced 8-Port Integrated Gigabit Ethernet Switch with Transceivers
GENERAL DESCRIPTION:
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, provides flexible QoS operation. This
is backed up by Layer 2-4 link aggregation and VLAN support, enabling
managed switches to be deployed.
A Vitesse Switch Family Member
SparX-G8e is a part of the Vitesse SparXTM Family Of Unmanaged or
Web-managed Switches, taking the family into a new generation of
integration. With its eight integrated tri-speed Gigabit Ethernet copper
transceivers (with the option of multiplexing two as tri-speed RGMII/GMII),
and several integrated management interfaces, it is specifically targeted at
SMB and SOHO unmanaged applications; with its V-Core CPU (on-chip
8051) and parallel CPU interface, it enables Web-managed and managed
switch applications.
With its unique low power dissipation, the VSC7398 enables fanless
operation, thereby providing higher system reliability and lower noise, both
to the benefit of the user.
Designing with Vitesse SparX Family Of Switches means designing with
the complete Vitesse solution: Vitesse provides a comprehensive, Webmanaged switch software system for the V-Core CPU (internal 8051). This
is in addition to the unmanaged and smart managed software systems for
8051, which are also included. For homegrown software development, the
Vitesse 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. The Vitesse solution is supplied with a
comprehensive collateral package, including software source code, full
documentation, and an in-depth qualification report for easy preevaluation.
Being a member of the switch family provides a number of unique
advantages when designing with the chip: there is nearly 100% software
compatibility between the switch family members; software written for
SparX-G8e can easily be used with other switch configurations in the
family, and vice-versa; and with minimal effort and time, designs can be
upgraded to higher port counts, or migrated to other configurations or
future technology. Building a product family is easy when designing with
Vitesse switches!
The switches provide for high performance designs
with their nonblocking, wire-speed performance,
which includes wire-speed MAC address learning.

The Vitesse SparXTM Family Of Switches
SparX-G8e shares the unique traits of the Vitesse SparX Family Of
Switches. The highly integrated switch supports 136 kilobytes of on-chip
frame buffer, and the integration of the copper PHY
as well as an internal oscillator circuit simplifies PCB
layout to reduce time and cost. Further trimming
down system cost is the industry's lowest power, fully
Shared Rx and
integrated, Switch-plus-Copper PHY technology.

VSC7398
Designing both unmanaged and Web-managed solutions is
straightforward. The chips offer an internal V-Core CPU (on-chip 8051)
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.
VSC7398 SparX-G8e is the highly integrated, singlechip Gigabit Ethernet switch with 8 Integrated GbE
Copper PHY ports. As part of the Vitesse SparXTM
Family of Switches, SparX-G8e delivers high
performance with easy migration paths, and
comprehensive system solutions that enable ultrashort time-to-market and market-leading system cost.
