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. 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. 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 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. 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. 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 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.
