SparX-G8™ – 8-port Integrated Gigabit Ethernet Switch SoC with Copper PHYs
GENERAL DESCRIPTION:
VSC7388 SparX-G8™ is the most highly integrated, single-chip Gigabit Ethernet switch with 8 Integrated GbE Copper PHY ports. As part of Vitesse’sSparX™ Family of switches, SparX-G8 delivers high performance with easy migration paths, and comprehensive System Solutions that enable ultra-short time-to-market and market leading system cost.
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 VSC7388 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 complete Vitesse Solution: Vitesse provides a comprehensive, web managed switch software system for the on-chip 8051 CPU. This is in addition to the unmanaged and smart managed software systems for 8051, which are also included. For homegrown software development, Vitesse's full platform and OS independent switch API are 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.
A Vitesse Switch Family Member SparX-G8 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, 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-G8 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 SparX™ Family Of Switches SparX-G8, 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 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 non-blocking, wire-speed performance, which includes wirespeed 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.
