GS3441-INTE3Z

Video Processing Overview

The GS3441-INTE3Z is an extended reach adaptive cable equalizer with dual outputs, designed for serial digital video applications. It supports data rates from 125Mb/s to 2.97Gb/s, compliant with SMPTE ST 424, ST 292, and ST 259 standards. The device operates on a single 3.3V supply, consuming typically 180mW with one output enabled and 212mW with both active. It features automatic cable equalization, DC restoration, and programmable squelch thresholds. The component is housed in a 24-pin QFN package (4mm x 4mm) and functions within a temperature range of -40°C to +85°C.

Video Processing Feature Summary

• Automatic adaptive cable equalization optimized for standard SDI data rates
• Dual independently-controlled differential outputs with adjustable swing and de-emphasis
• Programmable carrier detect with squelch threshold adjustment for noise immunity
• Cable length indicator output varying monotonically with input cable length

Video Processing Applications

• SMPTE ST 424, ST 292, and ST 259 coaxial cable serial digital interfaces
• Long-reach distribution of 3G/HD/SD video signals over 75Ω coaxial cable
• Broadcast equipment requiring signal restoration and equalization

Video Processing Procurement Notes

Verify the specific ordering suffix INTE3Z corresponds to the tape-and-reel packaging configuration as defined by Semtech. Confirm that the RoHS compliance status matches current regulatory requirements for your region. Ensure the QFN-24 footprint dimensions align with your PCB design guidelines before finalizing procurement orders.

Video Processing Selection Notes

Select this component when dual independent outputs are required for signal distribution. It is suitable for applications needing manual bypass capabilities or specific de-emphasis settings to compensate for PCB trace losses. Consider the GAIN_SEL pin if pre-equalization attenuation compensation is necessary for the input signal path.

Video Processing Part Context

This part belongs to Semtech's family of high-speed BiCMOS equalizers designed for serial digital video. It complements other signal integrity solutions like reclockers and cable drivers. The GS3441 provides extended reach capabilities compared to standard equalizers, making it distinct within the broadcast video semiconductor portfolio.

Video Processing Replacement Considerations

The datasheet notes footprint compatibility with the GS2993 equalizer. Verify electrical parameter alignment and pin-to-pin functionality before substituting.
