VSC7385 SparX-G5TM is the most highly integrated,
single-chip Gigabit Ethernet switch with 5 Integrated
GbE Copper PHY ports. As part of Vitesse'sSparXTM
Family of switches, SparX-G5 delivers high performance
with easy migration paths, and comprehensive System
Solutions that enable ultra-short time-to-market and
market leading system cost.
A Vitesse Switch Family Member
SparX-G5 is a part of the Vitesse SparXTM Family Of
Unmanaged or Web-managed Switches and takes the family
into a new generation of integration. With its 5 tri-speed
Gigabit Ethernet copper ports, it is specifically targeted at
SMB and SOHO unmanaged applications, and with its 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, including
nearly 100% software compatibility between members. Thus,
software written for SparX-G5 can easily be 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 minimum effort and time.
The Vitesse SparXTM Family Of Switches
VSC7385, as part of the Vitesse SparX Family Of Switches,
shares the unique traits of the family.
The highly integrated switches require no external memory at
all, and the integration of copper PHY as well as internal
oscillator circuits simplifies PCB layout to reduce time and
cost. Further trimming down system cost is the persistently
low power dissipation of the family.
The switches provide for high performance designs with their
non-blocking, wire-speed performance, which includes wire-
speed MAC address learning.
Designing both unmanaged and web-managed solutions is
straightforward. The chips offer both internal 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, 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 the VSC7385 enables fan less
operation and thereby provides for higher system reliability and
lower noise both 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 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 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.
