VSC7223XJV

Overview

The VSC7223XJV is a four-channel unidirectional adaptive channel extender manufactured by Microchip Technology. It operates as a multirate retimer and redriver supporting data rates up to 16 Gbps. The device integrates input equalization, clock and data recovery (CDR), and a continuous rate updater (CRU). It functions within a supply voltage range of 1.0 V to 1.2 V and dissipates power up to 180 mW. The component is housed in a 48-lead QFN package measuring 5x9 mm, designed for surface mount installation.

Feature Summary

• Integrates adaptive channel extension with continuous rate updating capabilities
• Incorporates input equalization and clock and data recovery circuits
• Supports multirate operation up to 16 Gbps per channel

Applications

• High-speed serial link signal integrity restoration
• Backplane interconnect applications requiring lane extension
• System-on-chip to board-level signal transmission

Procurement Notes

Verify the specific datasheet version and revision history prior to procurement, as Microchip may issue engineering changes or parameter updates. Confirm that the 48-QFN package dimensions and thermal requirements align with the target PCB layout. Ensure compliance with moisture sensitivity levels and reflow soldering profiles specified in the official handling guidelines to maintain device reliability during assembly.

Selection Notes

Select this component when designing systems requiring unidirectional signal regeneration over extended copper traces. The integrated CDR and equalization features address channel loss without requiring external discrete components. Consider the 16 Gbps maximum data rate capability and the 1.2 V operating voltage when evaluating power budgets and interface compatibility with upstream and downstream transceivers in high-performance networking architectures.

Part Context

This part belongs to the VSC722x family of adaptive channel extenders from Microchip Technology. These devices are engineered to extend the reach of high-speed serial links by compensating for insertion loss and jitter. The VSC7223XJV specifically targets applications needing four independent lanes of signal conditioning, providing a compact solution for maintaining signal integrity in dense electronic systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternative vendors, as pinouts, electrical characteristics, and control interfaces may differ significantly between manufacturers.
