VSC3144HR-02

Overview

The VSC3144HR-02 is a 6.5 Gbps 144 × 144 asynchronous crosspoint switch manufactured by Microchip Technology (formerly Vitesse). It provides 936 Gbps of aggregate bandwidth within a single chip, utilizing a fully non-blocking switch core programmed via a multimode port interface. The device supports differential CML I/O with integrated termination and operates on a 2.5 V power supply, with options for 3.3 V program port power. It accommodates CMOS TTL-compatible I/O levels and functions within an operating temperature range of 0 °C to 85 °C.

Feature Summary

• Strictly non-blocking 144 × 144 switch matrix supporting multicast and output striping programming modes
• Input signal equalization (ISE) with programmable control globally or per-channel, alongside adjustable output pre-emphasis EQ
• Protocol-independent switching allowing random access programming of each I/O port without phase or frequency restrictions
• Software-controlled power-down capability for unused channels to optimize overall power dissipation

Applications

• Core and Metro transport networks
• High-speed automated test equipment
• Broadcast video systems
• Storage, Ethernet, and networking equipment

Procurement Notes

Verify the specific suffix HR-02 against the manufacturer's current documentation to confirm package type and environmental rating. Confirm availability status as legacy products may have limited supply chains. Ensure compatibility with existing system voltage requirements and thermal management solutions before procurement.

Selection Notes

Select this component for high-density applications requiring protocol-independent switching at 6.5 Gbps per channel. Consider the 1072-pin BGA package constraints and the need for precise PCB layout to manage signal integrity. Evaluate if the 16 W typical power dissipation aligns with the system's thermal budget and cooling capabilities.

Part Context

The VSC3144 belongs to the Vitesse Semiconductor crosspoint switch family, now part of Microchip Technology. This series addresses high-bandwidth switching needs in telecommunications and data infrastructure. The device enables flexible interconnection between multiple standards and protocols, serving as a central switching element in complex network architectures.

Replacement Considerations

Consult official Microchip/Vitesse documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical specifications when considering alternative crosspoint switches from other manufacturers.
