A Vitesse Switch Family Member
SparX-G24 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 16 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-G24 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-G24, as part of the Vitesse SparX Family of Switches,
S P E C I F I C A T I O N S :
425-MHz, 125-MHz LVTTL Reference Clock
43.3 V Interface Power Supply
41.2 V Core Power Supply
4Thermally Enhanced PBGA Package
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-G24 enables the
customer to provide advanced features without the need of
enterprise class silicon.
24-Port Integrated Layer-2 Gigabit Ethernet Smart Switch with Transceivers
rehensive system solutions that enable ultra-short
time-to-market and market-leading system cost.
VSC7390 SparX-G24™ 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-G24 delivers high per-
formance with easy migration paths, and comp-
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-G24 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.
