VSC3316EV

Overview

The VSC3316EV is a multichannel crosspoint switch manufactured by Microsemi, now part of Microchip Technology. It supports data rates from DC to 11.5 Gbps per channel with a 16 × 16 fully non-blocking switch core. The device operates on a single 2.5 V power supply and utilizes a 15 mm × 15 mm flip chip ball grid array package. It provides protocol-transparent operation for asynchronous physical layer switching. Key signal integrity features include programmable input equalization up to 26 dB and output pre-emphasis of 9 dB. The architecture supports low latency of less than 1 ns.

Feature Summary

• Protocol-transparent operation allows independent channel running across various standard and proprietary data protocols.
• Advanced signal conditioning includes fourth-generation input equalization and output pre-emphasis to overcome channel impairments.
• Fully non-blocking multicasting switch core enables signal fanout, loopback, and protection switching functions.

Applications

• Servers
• Storage systems
• Telecom infrastructure
• Broadcast video switching and routing
• HDMI/DVI/DisplayPort switching and routing

Procurement Notes

Verify the specific suffix EV against official Microchip documentation to confirm exact package type and temperature range. Confirm current availability status as product lifecycles may change. Ensure compatibility with existing system voltage requirements of 2.5 V. Validate that the 15 mm × 15mm package fits the target PCB footprint. Check for any recent engineering change notices affecting pin definitions or electrical characteristics.

Selection Notes

Select this component for high-density copper interconnects requiring multi-gigabit data rates up to 11.5 Gbps. Consider the device for applications needing protocol transparency and low latency under 1 ns. Evaluate the need for extensive equalization capabilities to mitigate transmission medium losses. Ensure the design supports the required 2.5 V power supply domain. Assess if the 16 × 16 matrix size meets the routing complexity requirements.

Part Context

The VSC3316 belongs to the VSC3316 family of advanced signal conditioning crosspoint switches. This series addresses asynchronous physical layer switching needs in storage, server, and video industries. The device integrates a multicasting switch core with independent port operation. It is designed to regenerate signals compromised by transmission losses. The family supports virtually all standard and proprietary data protocols at maximum rates.

Replacement Considerations

Consult official Microchip documentation for confirmed substitute part numbers. Verify functional equivalence regarding data rate, pinout, and package dimensions. Ensure replacement parts maintain the same 2.5 V operating voltage and signal integrity specifications.
