GS1574-CNE3

Video Processing Overview

The GS1574-CNE3 is a high-speed bipolar integrated circuit designed to equalize and restore serial digital signals received over 75Ω coaxial cable. It supports SMPTE 292M, SMPTE 344M, and SMPTE 259M standards with automatic cable equalization across data rates from 143Mb/s to 1.485Gb/s. The device features DC restoration, programmable mute thresholds, and manual bypass modes. Powered by a single 3.3V supply, it consumes approximately 270mW and operates within a temperature range of 0°C to +70°C.

Video Processing Feature Summary

• Automatic cable equalization for serial digital interfaces
• DC restoration to compensate for pathological test patterns
• Programmable output mute based on maximum cable length adjustment
• Manual bypass mode for low data rate applications

Video Processing Applications

• SMPTE 292M Coaxial Cable Serial Digital Interfaces
• SMPTE 344M Coaxial Cable Serial Digital Interfaces
• SMPTE 259M Coaxial Cable Serial Digital Interfaces

Video Processing Procurement Notes

Verify the manufacturer origin as Gennum Corporation, noting that Semtech has acquired Gennum's assets. Confirm the specific suffix -CNE3 indicates the lead-free, RoHS-compliant version in the 16-pin QFN package. Check current availability status as this component may be subject to lifecycle changes or obsolescence notices.

Video Processing Selection Notes

Select this component for applications requiring adaptive equalization of SDI signals over coaxial cables. Ensure the design accommodates the 4mm x 4mm QFN package dimensions and thermal requirements. Verify compatibility with the required data rates and standard compliance needs before integration into the system architecture.

Video Processing Part Context

This part belongs to the GS1574 series of HD-LINX II Adaptive Cable Equalizers. It is functionally compatible with the GS9074 Cable Equalizer regarding pinout. The device represents a second-generation solution for restoring signal integrity in professional video transmission environments using standard coaxial cabling infrastructure.

Video Processing Replacement Considerations

The GS1574A is a compatible successor offering future-proofing for new designs while maintaining functional overlap.
