TDP142IRNQT

Specialized Overview

The TDP142IRNQT is a DisplayPort linear redriver manufactured by Texas Instruments, designed for high-speed display interface applications. It supports data rates up to 8.1 Gb/s and complies with the DP 1.4 specification. The device operates on a single 3.3 V power supply, with an acceptable voltage range of 3 V to 3.6 V. It draws a maximum operating current of 200 mA. The component is housed in a 40-pin WQFN package and is rated for an industrial temperature range from 0°C to +70°C. Configuration is managed via an I2C interface.

Specialized Feature Summary

• Linear signal amplification for DisplayPort links
• I2C programmable configuration control
• ESD protection integrated within the design

Specialized Applications

• DisplayPort 1.4 source and sink devices
• High-resolution monitor interfaces
• Docking stations and hubs with display output

Specialized Procurement Notes

Verify the specific suffix 'RNQT' against the manufacturer's official documentation to confirm the tape and reel packaging quantity and moisture sensitivity level. Ensure the ordering part number matches the required temperature grade and package variant exactly as listed in the latest datasheet revision.

Specialized Selection Notes

Select this component when a linear redriver is required for DisplayPort 1.4 compliance at 8.1 Gbps. Compare the 0°C to +70°C operating range against system thermal constraints. Verify that the 40-WQFN footprint aligns with the PCB layout guidelines provided in the application notes.

Specialized Part Context

This part belongs to the TDP142 series of display interface ICs. It functions specifically as a linear redriver to extend cable lengths or compensate for trace loss in high-bandwidth video transmission paths. It complements other Texas Instruments display interface solutions such as retimers and switches.

Specialized Replacement Considerations

Direct pin-to-pin replacements should be verified against the official substitution list. Cross-reference the TDP142EVM development kit compatibility if evaluating alternative components for existing designs.
