TDP142IRNQR

Specialized Overview

The TDP142IRNQR is a DisplayPort 1.4 linear redriver manufactured by Texas Instruments, designed to extend the reach of high-speed display signals. It supports data rates up to 8.1 Gbps per lane and features four independent channels within a single package. The device operates on a single 3.3 V supply voltage and functions reliably across an industrial temperature range from -40°C to +85°C. It utilizes a 40-pin WQFN (6x4 mm) surface-mount package with exposed thermal pad for efficient heat dissipation. The component integrates I2C control interface for configuration management.

Specialized Feature Summary

• Supports DisplayPort 1.4 compliance with 8.1 Gbps per-lane data rate capability
• Four-channel linear redriver architecture for signal integrity extension
• Integrated I2C interface for programmable configuration and monitoring
• Compact 40-pin WQFN package optimized for space-constrained designs

Specialized Applications

• DisplayPort source devices requiring signal re-driving
• High-resolution monitor interfaces extending cable length
• Docking stations and hubs with DisplayPort output
• Industrial display systems operating in extended temperature ranges

Specialized Procurement Notes

Verify the complete part number including suffix 'RNQR' to ensure correct tape-and-reel packaging quantity of 3000 units. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for latest product change notifications regarding pinout or electrical specifications before finalizing design files.

Specialized Selection Notes

Select this component when designing DisplayPort 1.4 interfaces requiring signal regeneration over PCB traces or cables. Ensure the host system provides stable 3.3 V power supply within specified tolerance. Verify that the application environment remains within the -40°C to +85°C operational range. Consider thermal performance due to the exposed pad requirement for adequate heat sinking.

Specialized Part Context

The TDP142 belongs to Texas Instruments' DisplayPort redriver family, addressing signal degradation in high-bandwidth video applications. It complements other interface solutions like USB Type-C redrivers by focusing specifically on display protocol requirements. The device enables designers to maintain signal quality without complex equalization algorithms.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified sources. Designers should consult Texas Instruments directly for qualified alternatives or cross-reference options based on specific electrical and mechanical constraints.
