GS1524-CTDE3

Video Processing Overview

The GS1524-CTDE3 is a multi-rate SDI adaptive cable equalizer designed for serial digital interfaces. It operates on a single 3.3V supply with typical power consumption of 265mW and current draw of 80mA. The device supports data rates from 143Mb/s to 1.485Gb/s, including DVB-ASI at 270Mb/s. It features automatic cable equalization, DC restoration, and a Cable Length Indicator (CLI). Operating temperature ranges from 0°C to +70°C. It is housed in a 16-pin SOIC package.

Video Processing Feature Summary

• Automatic cable equalization optimized for SMPTE 292M, 344M, and 259M standards
• Programmable mute output and analog cable length indicator for signal integrity management
• Manual bypass mode for low data rate applications with slow rise/fall times
• Single 3.3V power supply operation with RoHS compliance

Video Processing Applications

• SMPTE 292M Coaxial Cable Serial Digital Interfaces
• SMPTE 344M Coaxial Cable Serial Digital Interfaces
• SMPTE 259M Coaxial Cable Serial Digital Interfaces
• DVB-ASI transmission systems

Video Processing Procurement Notes

Verify the component manufacturer origin, as Gennum assets were acquired by Semtech. Confirm the specific tape packaging quantity associated with the CTDE3 suffix against current distributor listings. Ensure the operating temperature range matches the system requirements for the 0°C to +70°C specification.

Video Processing Selection Notes

Select this component for designs requiring adaptive equalization of SDI signals over coaxial cables up to specified lengths. It is suitable for environments where single-supply operation and compact SOIC packaging are required. Consider the CLI feature if monitoring cable attenuation is necessary for lower data rates.

Video Processing Part Context

This part belongs to the GS1524 series of high-speed bipolar integrated circuits. Originally manufactured by Gennum Corporation, the product line was transferred to Semtech Corporation following corporate acquisitions. The GS1524 represents a second-generation design focused on restoring signals received over 75Ω coaxial cable.

Video Processing Replacement Considerations

Check for direct equivalents within the GS15xx family or updated revisions from Semtech. Verify pin compatibility and electrical characteristics before substituting with other multi-rate SDI equalizers.
