Overview
The VSC3172JN-02 is a 6.5-Gbps asynchronous crosspoint switch manufactured by Microchip Technology, formerly Vitesse Semiconductor. It features a 72 × 72 strictly non-blocking matrix with an aggregate bandwidth of 468 Gbps. The device operates on a 2.5V power supply with 2.5V or 3.3V CMOS TTL-compatible I/O and supports differential CML data outputs with integrated termination. It functions within a 0 °C to 85 °C temperature range and utilizes a 613-pin FCBGA package.
Feature Summary
- Supports protocol-independent switching with programmable input equalization and output pre-emphasis for signal integrity optimization.
- Enables software-controlled power reduction for unused ports to minimize overall system energy consumption.
- Offers flexible configuration through parallel and serial programming modes for efficient control and monitoring.
Applications
- Core and metro transport networks
- Enterprise storage and Ethernet systems
- Blade server infrastructure
- High-speed automated test equipment
Procurement Notes
Verify the specific suffix JN-02 against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications. Cross-reference the datasheet revision history to ensure alignment with current manufacturing standards before procurement.
Selection Notes
Select this component for high-density networking applications requiring low latency and strict non-blocking performance. Evaluate the thermal requirements given the 10-W typical power dissipation and ensure the PCB layout accommodates the large 613-pin FCBGA footprint.
Part Context
This part belongs to the VSC3172 family of asynchronous crosspoint switches designed for broadband data streams. Originally developed by Vitesse Semiconductor, the product line was acquired by Microchip Technology, which continues to support these high-performance interconnect solutions.
Replacement Considerations
Consult the manufacturer's official documentation for confirmed substitute part numbers. Verify that any alternative maintains the 72x72 configuration and 6.5 Gbps data rate specifications.
