Overview
The VSC7389XHO is a 16-port integrated Layer-2 Gigabit Ethernet smart switch from the SparX-G16 family. It features 8 tri-speed copper transceivers compliant with IEEE 802.3ab and 8 SGMII ports. The device includes a 4500 kb on-chip frame buffer, supports jumbo frames up to 12.2 k, and offers per-port data rate policing with 64 kbps granularity. Power requirements are 3.3 V for interface and 1.2 V for core logic.
Feature Summary
- Integrates 8 tri-speed copper PHYs and 8 SGMII ports within a single chip
- Includes an on-chip V-Core CPU for advanced management protocols
- Supports comprehensive QoS with DSCP remarking and classifier functions
- Provides non-blocking wire-speed performance without external memory
Applications
- 16-port unmanaged Gigabit Ethernet SMB/SME/SOHO switches
- 16-port web-managed smart Gigabit Ethernet SMB/SME/SOHO switches
- LAN edge products requiring standard priority generation
Procurement Notes
Verify component authenticity through authorized Microchip or Vitesse distributors. Confirm package type matches the thermally enhanced PBGA specification. Ensure supply chain partners provide valid traceability documentation. Check for moisture sensitivity handling requirements prior to assembly.
Selection Notes
Select this component for designs requiring high integration of copper and SGMII interfaces. The internal V-Core CPU enables managed applications without external processors. Consider the low power dissipation benefits for thermal management in compact enclosures.
Part Context
This part belongs to the Vitesse SparX family of switches, designed for easy migration between configurations. Software written for SparX-G16 can be ported to other family members. The architecture supports both unmanaged and web-managed operation modes.
Replacement Considerations
Consult official Microchip documentation for direct pin-to-pin replacements. Verify software compatibility if migrating to newer SparX family members. Ensure voltage levels match the 3.3 V interface and 1.2 V core requirements.
