VSC3303EV

Overview

The VSC3303EV is a 4-port, 8.5 Gbps asynchronous crosspoint switch designed for high-speed serial backplanes and cable interconnect applications. It features advanced signal equalization with dual time-constant programmable input and output pre-emphasis to reduce jitter and reverse signal degradation. The device operates on a 2.5 V core voltage with flexible 1.8 V, 2.5 V, or 3.3 V high-speed I/O supplies. Each active channel consumes approximately 200 mW of power. Configuration is managed via a standard two-wire serial interface.

Feature Summary

• Fully non-blocking architecture supporting multicast and loopback capabilities
• Programmable multiple time-constant input equalization and output pre-emphasis
• Loss of signal (LOS) detection with forwarding functionality
• Transparent support for various data rates without external reference clocks

Applications

• Wideband signal switching and clean-up
• Backplane signal fanout, driver, or receiver
• Copper cable interconnects
• PCB signal enhancement
• High-speed signal conditioning

Procurement Notes

Verify the specific suffix 'EV' against official Microsemi documentation to confirm exact package type and temperature range. Confirm current availability status as product lifecycles may change. Ensure compatibility with existing system power rails and serial interface protocols before procurement.

Selection Notes

Select this component when asynchronous operation and protocol transparency are required. The integrated equalization addresses transmission line effects in PCBs and cables. Verify that the 4x4 port count meets system routing needs and that the BGA package fits the board layout constraints.

Part Context

The VSC3303 series provides a compact solution for high-speed signal routing within communication and industrial systems. It serves as a bridge between ASICs, FPGAs, and backplanes, enabling flexible signal distribution without complex clocking schemes.

Replacement Considerations

Check for updated Microsemi part numbers with revised suffixes. Evaluate related products like the VSC3303YHV if different packaging is required. Ensure any substitute maintains the 8.5 Gbps bandwidth and asynchronous architecture.

FAQ

Does the VSC3303 require an external reference clock?

No, the device uses a fully asynchronous architecture, allowing it to support any data rate or protocol without an external reference clock.

How is the device configured?

Configuration is performed through a standard two-wire serial interface, which can be addressed via static pins or a proprietary two-pin interface after power-up.

What is the typical power consumption per channel?

Typical power consumption is 200 mW per active channel. Unused channels can be deactivated to save power.
