GENERAL DESCRIPTION:
SPECIFICATIONS:
A Vitesse Switch Family Member
SparX-G5e is a part of the Vitesse SparX
TM
Family Of Unmanaged or
Web-managed Switches, taking the family into a new generation of
integration. With its five integrated tri-speed Gigabit Ethernet copper
transceivers, one 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.
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-G5e 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 Vitesse SparX
TM
Family Of Switches
SparX-G5e 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
integrated, Switch-plus-Copper PHY technology.
The switches provide for high performance designs
with their nonblocking, wire-speed performance,
which includes wire-speed MAC address learning.
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.
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.
With its unique low power dissipation, the VSC7395 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, Web-
managed 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 pre-
evaluation.
SparX-G5e
TM
-Enhanced 5 + 1-Port Integrated Gigabit Ethernet Switch with Transceivers
VSC7395 SparX-G5e is the highly integrated, single-
chip Gigabit Ethernet switch with 5+1 Integrated GbE
Copper PHY ports. As part of the Vitesse SparX
Family of Switches, SparX-G5e delivers high
performance with easy migration paths, and
comprehensive system solutions that enable ultra-
short time-to-market and market-leading system cost.
