VSC8228RCEV-01

Overview

The VSC8228RCEV-01 is a dual-channel multirate signal conditioner and retimer designed for Fibre Channel, Gigabit Ethernet, SONET/SDH, and InfiniBand applications. It features dual FibreTimer clock recovery units (CRU) supporting data rates from 125 Mbps to 4.25 Gbps. The device operates on a single 1.2 V or 1.8 V supply, with typical power dissipation of 360 mW at 1.2 V. Packaged in a 10 mm x 10 mm, 64-pin TQFP, it provides bidirectional signal conditioning via configurable repeater, retimer, or bypass modes.

Feature Summary

• Dual FibreTimer Clock Recovery Units (CRU) for bidirectional signal conditioning
• Configurable operation modes: Retimer, Repeater, or Bypass
• Programmable input equalization, output de-emphasis, and drive levels
• Built-in self-test with PRBS generation/detection up to 2^31

Applications

• Fibre Channel switches and disk arrays
• Gigabit Ethernet line cards
• Blade server backplanes
• RAID subsystems and host bus adapters

Procurement Notes

Verify the specific suffix 'RCEV-01' against official Microsemi documentation to confirm package type and temperature range. Confirm RoHS compliance status through current datasheets as product specifications are subject to change without notice.

Selection Notes

Select this component for high-speed serial interconnects requiring jitter reduction and signal integrity restoration. Ensure the design supports CML inputs/outputs and AC coupling if LVPECL or LVDS compatibility is required. Verify that the system can accommodate the 1.2 V or 1.8 V power supply requirements.

Part Context

The VSC8228 is part of Microsemi's portfolio of high-performance analog mixed-signal integrated circuits.

FAQ

What are the supported data rates for the VSC8228?

The device supports data rates ranging from 125 Mbps up to 4.25 Gbps.

How does the retimer mode handle timing differences?

In retimer mode, add/drop elasticity buffers insert or delete Fibre Channel fill words to account for timing differences between the incoming data and the local reference clock.

What diagnostic features are included?

The device includes an analog signal detect function, protocol monitor indicators, and a built-in pattern generator/checker capable of generating and detecting various PRBS patterns and Fibre Channel test patterns.
