Overview
The VSC3172XJN-12 is a 6.5-Gbps 72 × 72 asynchronous crosspoint switch designed for high-density network storage, fiber channel, blade server, and Ethernet systems. It features a fully non-blocking switch core with an aggregate bandwidth of 468 Gbps per chip. The device operates on a 2.5V power supply with 2.5V or 3.3V CMOS TTL-compatible I/O and differential CML I/O with integrated termination impedance. It supports an operating temperature range from 0 °C to 85 °C and utilizes a 613-pin FCBGA package measuring 33 mm × 33 mm with a 1.27 mm pin pitch.
Feature Summary
- Strictly non-blocking 72x72 switch matrix supporting multicast and output striping programming modes
- Fourth-generation input signal equalization (ISE) with programmable control globally or per-channel
- Adjustable output pre-emphasis EQ and differential current mode logic (CML) data output driver
- Parallel and serial programming modes for configuration and monitoring
Applications
- Core and Metro transport networks
- Enterprise networking equipment
- Blade servers
- High-speed automated test equipment
- Broadcast video systems
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Confirm availability status directly with authorized distributors as inventory levels fluctuate. Ensure compatibility with existing system voltage requirements before procurement.
Selection Notes
Select this component for applications requiring high-density, protocol-independent switching at 6.5 Gbps. Consider its low power dissipation of 140 mW per channel and flexible programming interface when designing PCB layouts for backplane or board-level interconnects.
Part Context
The VSC3172 series represents a high-performance asynchronous crosspoint switch solution. Manufactured originally by Vitesse Semiconductor, now part of Microchip Technology, it addresses signal integrity and intersymbol interference issues in next-generation networking environments.
Replacement Considerations
Check for updated Microchip part numbers within the same product family. Verify pinout and electrical specifications match exactly if substituting with other 72x72 crosspoint switches.
