GS6042-INE3

Specialized Overview

The GS6042-INE3 is a 6G UHD-SDI/3G/HD/SD adaptive cable equalizer designed for high-speed signal recovery over 75-ohm coaxial cables. It supports data rates from 125Mb/s to 6.25Gb/s, complying with SMPTE ST 2081, ST 424, ST 292, and ST 259 standards. Typical equalized lengths for Belden 1694A cable are 80m at 5.94Gb/s, 210m at 2.97Gb/s, 300m at 1.485Gb/s, and 500m at 270Mb/s. The device operates on a single +3.3V supply with 180mW power consumption (35mW in sleep). It features automatic cable equalization, manual bypass control, programmable carrier detect, and differential CML outputs supporting DC-coupling from +1.2V to +3.3V. The component is housed in a small footprint 16-QFN package (4mm x 4mm) and operates within a temperature range of -40ºC to +85ºC.

Specialized Feature Summary

• Automatic cable equalization optimized for multiple SDI standards including 6G UHD-SDI and 3G HD/SD
• Supports DVB-ASI at 270Mb/s and MADI at 125Mb/s with manual bypass control for low data rates
• Differential output supports DC-coupling from +1.2V to +3.3V CML logic with selectable de-emphasis
• Footprint compatible with GS2974A, GS2974B, GS2984, GS2994, and GS3440 series

Specialized Applications

• 6G UHD-SDI signal distribution and transmission systems
• 3G/HD/SD video infrastructure requiring long cable runs
• Broadcast equipment utilizing DVB-ASI or MADI interfaces

Specialized Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration. The INE3 designation indicates lead-free and RoHS compliance. Confirm the reel quantity matches production requirements, as variations exist between cut tape, standard reels, and larger volume packaging options. Ensure the design accommodates the 16-QFN thermal pad requirements for proper heat dissipation during operation.

Specialized Selection Notes

Select this component when designing systems requiring adaptive equalization for 75-ohm coaxial cables up to 6.25Gb/s. It is suitable for applications needing compatibility with existing GS29xx and GS34xx footprints. Consider the power consumption profile if thermal management is constrained, noting the significant reduction in sleep mode. Verify that the input signal levels align with the supported CML logic ranges for optimal performance.

Specialized Part Context

The GS6042 is part of Semtech's Gennum product line focused on professional video interface solutions. It serves as an adaptive equalizer to extend the reach of digital video signals over coaxial cabling. The device integrates automatic equalization algorithms to compensate for cable loss without external configuration, simplifying system design for broadcast and professional AV installations.

Specialized Replacement Considerations

The GS6042 is footprint compatible with the GS2974A, GS2974B, GS2984, GS2994, and GS3440. Verify pinout and functional equivalence before substitution, as these parts may have different speed capabilities or feature sets despite shared physical dimensions.
