GS2984-INTE3D

Video Processing Overview

The GS2984-INTE3D is a high-speed BiCMOS integrated circuit designed as a 3G-SDI adaptive cable equalizer. It supports SMPTE 424M, SMPTE 292M, and SMPTE 259M standards, optimized for data rates of 270Mb/s, 1.485Gb/s, and 2.97Gb/s. The device features automatic cable equalization to compensate for signal loss over 75-ohm coaxial cables, extending reach up to 140m at 3Gb/s. It includes DC restoration for pathological test patterns and a carrier detect output for mute control. The component operates within a temperature range of -40°C to +85°C and is housed in a 16-pin QFN package.

Video Processing Feature Summary

• Automatic cable equalization for extended transmission distances
• DC restoration capability for SMPTE pathological test patterns
• Carrier detect output with voltage programmable threshold
• Footprint and drop-in compatible with existing GS2974 designs

Video Processing Applications

• Restoring signals received over 75-ohm coaxial cable
• Compensating for insertion loss in professional video distribution systems
• Signal conditioning for SMPTE 424M, 292M, and 259M compliant equipment

Video Processing Procurement Notes

Verify the specific suffix 'D' against official Semtech documentation, as standard listings often reference GS2984-INTE3. Confirm current availability status, as this component may be subject to discontinuation or limited supply. Ensure the selected variant matches the required operating temperature range and package specifications for your design.

Video Processing Selection Notes

Select this component when designing systems requiring equalization for long-reach 3G-SDI signals over coaxial cabling. It serves as a direct replacement for the GS2974 without requiring application changes. Consider its low power consumption and compatibility with industry-standard CML logic levels when integrating into receiver chains.

Video Processing Part Context

The GS2984 belongs to Semtech's portfolio of high-speed BiCMOS video interface solutions. It is part of the broader family of SDI signal conditioning devices, positioned alongside reclockers and drivers. This specific model focuses on passive equalization and DC restoration rather than active retiming.

Video Processing Replacement Considerations

The GS2984 is footprint and drop-in compatible with the GS2974. For new designs, Semtech recommends using the GS2994.
