TDP142RNQR

Specialized Overview

The TDP142RNQR is a DisplayPort linear redriver manufactured by Texas Instruments, designed for high-speed display interface applications. It supports data rates up to 8.1 Gbps per lane, compliant with DisplayPort 1.4 specifications. The device operates within an ambient temperature range of -40°C to +85°C and utilizes a 40-pin WQFN package (6x4 mm) suitable for surface mount technology. Powered by a single supply voltage typically around 3.3V, it integrates input equalization and output pre-emphasis capabilities to compensate for signal loss in PCB traces. This component functions as a passive or active repeater to extend link distance and maintain signal integrity in complex display architectures.

Specialized Procurement Notes

Verify the specific ordering suffix 'R' confirms the reel packaging format when sourcing from distributors. Ensure compatibility with existing PCB footprint dimensions for the 40-WQFN package. Cross-reference the manufacturer part number against official datasheets to confirm revision levels. Validate that the supplier provides genuine components with traceability documentation. Check for any specific handling requirements related to moisture sensitivity levels indicated in the datasheet.

Specialized Selection Notes

Select this component when designing systems requiring compliance with DisplayPort 1.4 electrical standards. Consider the 8.1 Gbps bandwidth limit relative to the target resolution and refresh rate requirements. Evaluate the power consumption profile against system thermal constraints. Assess the need for integrated equalization features versus external solutions based on trace length and material properties. Confirm the operating temperature range meets the environmental conditions of the final application.
