TDP142RNQT

Specialized Overview

The TDP142RNQT is a DisplayPort linear redriver manufactured by Texas Instruments, designed for high-speed signal integrity in display interfaces. It supports data rates up to 8.1 Gbps, compliant with DP 1.4 specifications. The device operates on a single 3.3 V supply voltage, with an acceptable range of 3.0 V to 3.6 V. It features four channels and utilizes an I2C interface for configuration. The component is housed in a 40-WQFN package (6x4 mm) and operates within a temperature range of 0°C to +70°C. Typical operating current is 200 mA.

Specialized Feature Summary

• Linear amplification technology for low-latency signal regeneration
• Integrated equalization and pre-emphasis capabilities
• Configurable via standard I2C control interface

Specialized Applications

• DisplayPort source devices requiring signal extension
• High-resolution monitor input stages
• Docking stations and hub interfaces

Specialized Procurement Notes

Verify the specific suffix 'QT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering part number matches the exact pinout and electrical characteristics required for the target design, as variations exist within the TDP142 family.

Specialized Selection Notes

Select this component when a low-latency linear solution is preferred over decision-tree equalizers for DisplayPort 1.4 links. Confirm that the PCB layout accommodates the 40-pin WQFN footprint and that the power budget supports the 200 mA typical consumption at 3.3 V.

Specialized Part Context

This part belongs to the TDP142 series of display interface ICs from Texas Instruments. It serves as a bridge component to extend trace lengths or improve signal quality in digital display connections. The RNQT designation indicates the specific reel packaging format used for surface-mount assembly.
