GS2974BCNTE3

Video Processing Overview

The GS2974BCNTE3 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, with performance optimized for data rates of 270 Mbps, 1.485 Gbps, and 2.97 Gbps. The device features DC restoration to compensate for pathological test patterns and includes a Carrier Detect output that enables automatic power-down upon signal loss. It operates on a single +3.3 V supply, consumes typically 166 mW when DC-coupled at 1.2 V, and is housed in a 16-pin, 4 mm x 4 mm QFN package.

Video Processing Feature Summary

• Automatic cable equalization for 75-ohm coaxial transmission
• DC restoration for SMPTE pathological test pattern compensation
• Automatic power-down via carrier detect logic
• Footprint compatible with GS2974 and GS2984 designs

Video Processing Applications

• SDI signal reception and restoration
• Broadcast video infrastructure
• Professional AV equipment

Video Processing Procurement Notes

Verify the specific suffix 'BCNTE3' against official Semtech documentation to confirm exact packaging and RoHS compliance status. Confirm current availability as distribution channels may list this component as discontinued or limited stock. Ensure the ordering information matches the required tape-and-reel quantity and moisture sensitivity level for your assembly process.

Video Processing Selection Notes

Select this component for applications requiring standardized SDI equalization without complex external circuitry. It is suitable for systems needing drop-in replacement for legacy GS2974 or GS2984 designs. Consider its single-supply operation and low power consumption for compact or battery-sensitive professional video equipment.

Video Processing Part Context

The GS2974 series belongs to Semtech’s family of high-speed BiCMOS interface ICs. These devices are engineered specifically for the broadcast and professional video industry to handle serial digital interface (SDI) signals. The series provides reliable signal integrity over long coaxial runs while maintaining compatibility with standard SMPTE specifications.

Video Processing Replacement Considerations

The GS2974BCNTE3 is footprint and drop-in compatible with existing GS2974 and GS2984 designs.
