VSC3308EV

Overview

The VSC3308EV is an advanced signal conditioning crosspoint switch manufactured by Microsemi, now part of Microchip Technology. It features an 8 × 8 fully non-blocking switch core with ports capable of operating at data rates up to 11.5 Gbps. The device supports protocol-transparent operation, allowing each channel to run independently across asynchronous and physical layer switching applications. Key electrical specifications include a 2.5 V power supply requirement and a 10 mm × 10 mm flip chip ball grid array package. It incorporates fourth-generation input equalization and pre-emphasis I/O capability engineered to overcome channel impairments in high-density systems.

Feature Summary

• Protocol-transparent operation supporting virtually all standard and proprietary data protocols up to the maximum data rate
• Advanced signal integrity management with multiple time-constant programmable input and output equalization
• Fully asynchronous architecture with less than 1 ns latency and loss-of-signal detection
• Supports signal fanout, loopback, and protection switching functions

Applications

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

Procurement Notes

Verify the specific suffix EV against official Microchip documentation to confirm exact package type, temperature range, and lead-free status. Confirm current availability as product lifecycles may change. Ensure compliance with moisture sensitivity levels during handling. Cross-reference datasheet revisions for any updates to electrical parameters or pin assignments before finalizing procurement orders.

Selection Notes

Select this component for high-speed copper interconnect solutions requiring cost-effective signal regeneration. The device is suitable for applications needing independent channel operation without protocol dependency. Consider the 26 dB input equalization and 9 dB pre-emphasis capabilities when designing for channels with significant dispersion losses. Ensure system design accommodates the 2.5 V supply voltage and appropriate thermal management for the FC-BGA package.

Part Context

The VSC3308 belongs to the Vitesse Semiconductor crosspoint switch family, acquired by Microsemi and subsequently integrated into Microchip Technology's portfolio. This series addresses high-speed asynchronous switching needs in data center and communication environments. The device serves as a key building block for backplane and line card applications where low latency and high port density are critical requirements.
