VSC3340YJJ-01

Overview

The VSC3340YJJ-01 is a 6.5 Gbps non-blocking crosspoint switch manufactured by Microchip Technology (formerly Microsemi). It features a 40 × 40 switch core supporting protocol-independent operation with asynchronous data rates up to 6.5 Gbps NRZ per channel. The device operates on a single 2.5 V power supply and utilizes a 23 mm × 23 mm flip-chip ball grid array package. Key signal integrity specifications include programmable input equalization providing up to 26 dB at maximum speed and 9 dB of output pre-emphasis. The architecture supports low-latency switching, multicasting, and advanced low-power green modes.

Feature Summary

• Protocol-transparent operation allowing independent channel optimization across storage, video, and communication applications
• Advanced signal conditioning with programmable input equalization and output pre-emphasis to compensate for channel impairments
• Fully non-blocking multicasting switch core enabling signal fanout, loopback, and protection switching functions

Applications

• HDMI/DVI/DisplayPort switching and routing
• Broadcast video switching and routing
• PCIe repeater applications
• Servers and enterprise storage systems
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix 'YJJ' against official Microchip documentation to confirm pinout compatibility and package variations. Confirm current lifecycle status as distribution channels may list this component as obsolete or end-of-life. Ensure environmental compliance details match project requirements before finalizing procurement orders.

Selection Notes

Select this component for high-density copper interconnects requiring protocol independence and low latency. Evaluate the 40x40 matrix size against port count requirements to avoid over-specification. Consider the 2.5V supply constraint and thermal dissipation needs associated with the 23mm x 23mm package in dense system designs.

Part Context

This part belongs to the VSC3340 family of multichannel crosspoint switches designed for high-speed signal routing. It serves as a central switching element in line card and backplane architectures. The device replaces discrete mux/demux solutions by integrating signal regeneration and switching capabilities into a single integrated circuit.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify if other variants within the VSC3340 series offer compatible pinouts or if legacy Microsemi documentation lists direct replacements.
