VSC7395XYV

Overview

The VSC7395XYV is a SparX-G5e enhanced integrated Gigabit Ethernet switch featuring five tri-speed copper transceivers and one RGMII/GMII interface. It includes an on-chip 8051 CPU, 136 kilobytes of frame buffer, and supports SNMP/Web management. The device operates with a 1.2 V core supply and 3.3 V interface supply, utilizing a 25 MHz LVTTL reference clock. Packaged in a 364-BGA (23x23) format, it provides nonblocking wire-speed performance for SMB and SOHO applications.

Feature Summary

• Integrates five tri-speed copper PHYs and one high-speed MAC interface into a single chip to reduce system component count.
• Includes an internal V-Core 8051 processor enabling standalone Web-managed or unmanaged operation without external CPUs.
• Provides advanced QoS capabilities including DSCP remarking, multilayer classification, and support for IPv4/IPv6 frames.
• Supports comprehensive network protocols such as IEEE 802.1Q VLANs, 802.1D/w/s spanning tree, and 802.1X authentication.

Applications

• 5-port unmanaged Gigabit Ethernet SMB/SOHO switches
• 5-port Web-managed Gigabit Ethernet SMB/SOHO switches
• Broadband routers combining LAN switching with WAN uplinking

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with the required power supplies and reference clock frequencies before integration. Cross-reference the part number with current datasheets to validate any recent revisions or pinout changes.

Selection Notes

Select this component when designing cost-effective Gigabit Ethernet solutions requiring integrated PHYs and management capabilities. It is suitable for applications needing fanless operation due to low power dissipation. Consider the available software API and reference designs if rapid development is required for managed switch implementations.

Part Context

The VSC7395 belongs to the Vitesse SparX family of switches, offering high software compatibility across different port configurations. This family allows designers to migrate easily between unmanaged and managed products. The SparX-G5e variant specifically targets small business environments with its balance of performance and integration.

Replacement Considerations

Check for other members within the SparX family that may offer different port counts or interface options while maintaining software compatibility. Verify if alternative packages are available from the manufacturer for different board space requirements.
