GS2994-INE3

Video Processing Overview

The GS2994-INE3 is a high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75-ohm coaxial cable. It supports SMPTE 424M, SMPTE 292M, and SMPTE 259M standards, optimized for 270Mbps, 1.485Gbps, and 2.97Gbps data rates. The device features automatic cable equalization, DC restoration, and programmable de-emphasis. It operates on a single supply voltage with typical power consumption of 166mW when DC-coupled at 1.2V. The component is housed in a 16-pin, 4mm x 4mm QFN package.

Video Processing Feature Summary

• Automatic cable equalization for signal restoration
• DC restoration to compensate for pathological test patterns
• Programmable de-emphasis for long PCB traces
• Carrier detect with automatic power-down capability

Video Processing Applications

• SDI transmission systems requiring signal equalization
• Broadcast video infrastructure equipment
• Professional audio/video distribution networks

Video Processing Procurement Notes

Verify the specific suffix INE3 against official Semtech documentation to confirm lead-free and RoHS compliance status. Ensure the QFN-16 package dimensions match your PCB footprint requirements. Confirm that the serial interface control logic aligns with your system design before procurement.

Video Processing Selection Notes

Select this component for applications requiring drop-in compatibility with existing GS2974 and GS2984 designs. It is suitable for environments needing automatic equalization without manual adjustment. Consider its power consumption profile when designing thermal management solutions for dense enclosures.

Video Processing Part Context

The GS2994 belongs to Semtech's family of SDI cable equalizers. It complements other series members like the GS2993 and GS6042 by providing specialized equalization for standard definition through 3G-SDI signals. It serves as a critical link in maintaining signal integrity across coaxial cables in professional video environments.

Video Processing Replacement Considerations

Public confirmed substitute part numbers include GS2974 and GS2984 due to footprint and drop-in compatibility.
