Overview
The VSC3340EV is a multichannel crosspoint switch supporting data rates from DC to 6.5 Gbps per channel. It features a 40 × 40 fully non-blocking switch core with protocol-independent operation, allowing each port to run independently at varying speeds. The device incorporates fourth-generation input equalization and pre-emphasis I/O capability, providing 26 dB of input EQ and 9 dB of pre-emphasis. It operates on a single 2.5 V power supply and utilizes a 23 mm × 23 mm flip chip ball grid array package.
Feature Summary
- Supports signal fanout, loopback, and protection switching within the 40x40 architecture
- Provides advanced equalization to compensate for deterministic jitter across high-speed interconnects
- Enables low power green modes for optimized energy efficiency at lower data rates
Applications
- HDMI/DVI/DisplayPort switching and routing
- Broadcast video routers and switchers
- PCIe repeater applications
- Blade servers and storage servers
- Telecom backplane and line card systems
Procurement Notes
Verify component authenticity through authorized Microchip or Vitesse distribution channels. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Review current product lifecycle status as availability may be limited due to legacy classification.
Selection Notes
Select this component for designs requiring high-density signal routing up to 6.5 Gbps without protocol dependency. Ensure PCB layout accommodates the specific 23 mm × 23mm FCBGA footprint. Validate thermal management strategies given the 2.5 V operating voltage and high channel count density.
Part Context
Originally developed by Vitesse Semiconductor, this component was integrated into Microchip Technology’s portfolio following acquisition. It belongs to the VSC3340 family of high-performance crosspoint switches designed for demanding signal integrity challenges in enterprise and broadcast environments.
Replacement Considerations
Consult official Microchip documentation for direct pin-compatible substitutes. Evaluate newer generation crosspoint switches if long-term supply assurance is required, ensuring equivalent bandwidth and form factor compatibility.
