VSC3172XJN-02

Overview

The VSC3172XJN-02 is a 72 × 72 asynchronous crosspoint switch manufactured by Microchip Technology. It supports a data rate of 6.5 Gbps per channel, providing an aggregate bandwidth of 468 Gbps within a single chip. The device operates on a 2.5V power supply with 2.5V or 3.3V CMOS TTL-compatible I/O options. It features fully differential CML I/O with integrated termination impedance and maintains signal integrity through programmable input equalization and output pre-emphasis settings. The operating temperature range spans from 0 °C to +85 °C. The component is housed in a 613-pin FCBGA package measuring 33 mm × 33 mm with a 1.27 mm pin pitch.

Feature Summary

• Strictly non-blocking 72 × 72 switch matrix supporting multicast and output striping programming modes
• Fourth-generation input signal equalization (ISE) with global or per-channel programmable control
• Adjustable output pre-emphasis equalization for optimized signal transmission across various media
• Software-controlled power reduction capabilities allowing unused ports to be powered down

Applications

• Core and metro transport networks
• Enterprise networking infrastructure
• Blade server systems
• High-speed automated test equipment
• Broadcast video systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm voltage levels and package variants. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure compatibility with existing system power supplies and I/O standards before procurement.

Selection Notes

Select this component for high-density network storage, Fibre Channel, and Ethernet applications requiring protocol-independent switching. Evaluate the need for programmable equalization to address board-level signal integrity and intersymbol interference issues. Consider the low power dissipation per channel when designing thermal management solutions for dense deployments.

Part Context

The VSC3172 series represents a fourth-generation asynchronous crosspoint switch designed for high-bandwidth data streams. Manufactured originally by Vitesse Semiconductor Corporation, now part of Microchip Technology, these devices facilitate next-generation network implementations. The architecture supports unregistered, fully asynchronous signal paths without restrictions on phase or frequency.

Replacement Considerations

Consult official Microchip documentation for confirmed substitute part numbers. Verify that any alternative components maintain the 72 × 72 configuration and 6.5 Gbps per-channel data rate requirements.
