VSC3144XHR-12

Overview

The VSC3144XHR-12 is a 6.5 Gbps 144 × 144 asynchronous crosspoint switch manufactured by Microchip Technology. It features a fully non-blocking switch core with an aggregate bandwidth of 936 Gbps. The device operates on a 2.5 V power supply, with I/O supporting 2.5 V or 3.3 V CMOS TTL compatibility. It utilizes differential CML I/O with integrated termination and operates within a temperature range of 0 °C to +85 °C. The component is housed in a 1072-pin BGA package measuring 45 mm × 45 mm with a 1.27 mm pin pitch.

Feature Summary

• Strictly non-blocking switch matrix with multicast and output striping programming modes
• Input signal equalization (ISE) with programmable control globally or per-channel
• Adjustable output pre-emphasis EQ for driving boards, cables, and circuit traces
• Protocol-independent switching and data transmission

Applications

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

Procurement Notes

Verify the specific suffix against official documentation to confirm exact packaging and environmental ratings. Confirm current availability status as distribution channels may vary. Ensure the source document matches the manufacturer's latest revision to avoid discrepancies in electrical specifications or pinout definitions during integration.

Selection Notes

Select this component for high-density network switching requiring protocol-independent data transmission. Evaluate the 1072-pin BGA package constraints for PCB layout and thermal management. Consider the 16 W typical power dissipation and verify that the 2.5 V supply aligns with system power architecture requirements.

Part Context

This part belongs to the Vitesse Semiconductor crosspoint switch family, now under Microchip Technology. It serves as a central switching element for backplane applications, line cards, and FPGA interconnects. The device enables flexible signal routing without register restrictions, supporting various input frequencies and patterns simultaneously.

Replacement Considerations

Consult official product briefs for related Vitesse products. Verify pin-to-pin compatibility and electrical parameter alignment before substituting. Cross-reference datasheets to ensure equivalent bandwidth and package dimensions.
