MAX3980UGH

Specialized Overview

The MAX3980UGH is a quad equalizer designed for XAUI applications, providing compensation for transmission medium losses across four lanes of digital NRZ data at 3.125Gbps. It operates on a single 3V to 3.6V power supply and features a 44-QFN (7x7) package with an exposed pad. The device supports surface-mount installation and includes thermal performance enhancements via the exposed pad connection.

Specialized Feature Summary

• Provides signal equalization for four independent data lanes
• Compensates for channel insertion loss in high-speed serial links
• Supports standard XAUI interface specifications

Specialized Applications

• XAUI host board designs
• 20Gbps Quad-SFP active copper cable assemblies
• Quad-SFP host adapters

Specialized Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm RoHS compliance status as historical records may vary. Ensure storage conditions meet humidity sensitivity requirements prior to assembly. Validate package marking against official datasheet images to prevent counterfeit substitution.

Specialized Selection Notes

Select this component when designing systems requiring standardized XAUI connectivity at 3.125Gbps per lane. Consider the 44-QFN footprint for PCB layout constraints. Evaluate thermal dissipation needs due to the exposed pad requirement. Compare against alternative equalizers if higher data rates or different interface standards are required.

Specialized Part Context

This part belongs to the MAX3983 family of signal conditioners. While related to the MAX3983UGK+D, it specifically targets XAUI equalization rather than general copper-cable conditioning. It complements drivers like the MAX3980 series transmitters in complete link solutions.

Specialized Replacement Considerations

No direct public substitute part numbers are confirmed in available documentation. Designers should consult Analog Devices for current equivalent recommendations based on specific system requirements.
