GS1528-CTAE3

Video Processing Overview

The GS1528-CTAE3 is a second-generation high-speed bipolar integrated circuit designed to drive one or two 75Ω coaxial cables at data rates up to 1.485Gb/s. It provides dual selectable slew rates for compliance with SMPTE 259M, SMPTE 344M, and SMPTE 292M standards. The device accepts LVPECL level differential inputs that may be AC-coupled without external biasing resistors. Power consumption is typically 160mW using a single 3.3V power supply. Operating temperature range is 0°C to 70°C.

Video Processing Feature Summary

• Dual coaxial cable driving outputs with selectable slew rate
• Seamless interface to other HD-LINX II family products
• Self-biased differential input requiring no external biasing resistors

Video Processing Applications

Video Processing Procurement Notes

Verify the manufacturer origin as Gennum Corporation, noting current Semtech Corporation ownership of the HD-LINX portfolio. Confirm the specific suffix CTAE3 corresponds to the 8-pin SOIC package in tape and reel format containing 250 pieces. Ensure RoHS compliance status matches the ordering information provided in the datasheet.

Video Processing Selection Notes

Select this component when interfacing serial digital video signals requiring compliance with multiple SDI standards including SMPTE 259M, 344M, and 292M. The dual output capability supports driving two separate coaxial cables simultaneously. Verify that the system operates within the specified 0°C to 70°C temperature range and utilizes a 3.3V power supply.

Video Processing Part Context

This part belongs to the HD-LINX II family of high-speed bipolar integrated circuits. It functions specifically as a multi-rate SDI dual slew-rate cable driver. The product line focuses on providing compliant signal transmission for professional broadcast and video applications over coaxial cabling infrastructure.

Video Processing FAQ

How is the output slew rate controlled?

The output slew rate is controlled via the SD/HD logic input pin. Setting this pin HIGH configures the output for SMPTE 259M rise/fall time specifications, while setting it LOW configures the output for SMPTE 292M specifications.

What is the function of the RSET resistor?

The RSET resistor is used to adjust the output amplitude. A value of 750Ω is required to achieve a nominal 800mVp-p output swing into a 75Ω load.
