SN75DP129RHHR

Specialized Overview

The SN75DP129RHHR is a DisplayPort to TMDS translator manufactured by Texas Instruments. It converts DisplayPort signals into TMDS format for display interfaces. The device operates at a single supply voltage of 3.3 V with a maximum operating temperature of +85°C and a minimum of -40°C. It utilizes a WQFN-56 package suitable for surface-mount installation. Key electrical parameters include a propagation delay of 15 ns and an output current capability of 20 uA. The component functions as a dedicated interface IC for translating digital video signals between different standards.

Specialized Feature Summary

• Performs translation from DisplayPort input signals to TMDS output format
• Supports dual-mode repeater functionality within the SN75DP12x series family
• Designed for high-speed digital video signal conversion applications

Specialized Applications

• DisplayPort to HDMI adapter circuits
• Monitor and display driver boards requiring signal standard conversion
• Multimedia systems integrating DisplayPort sources with TMDS sinks

Specialized Procurement Notes

Verify the specific suffix RHHR against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure compatibility with the target PCB footprint and thermal requirements. Cross-reference the part number with authorized distributors to confirm authenticity and traceability before procurement.

Specialized Selection Notes

Select this component when a direct translation from DisplayPort to TMDS is required without external logic. Compare against similar translators in the SN75DP12x series for pin compatibility and feature sets. Verify that the 3.3 V supply voltage aligns with the system power architecture and that the WQFN-56 package fits the design constraints.

Specialized Part Context

This part belongs to the SN75DP12x series of display interface integrated circuits from Texas Instruments. The series includes related devices such as the SN75DP120 and SN75DP122, which offer varying combinations of switching and translation capabilities. These components are designed to facilitate interoperability between modern display ports and traditional TMDS-based displays.

Specialized Replacement Considerations

The SN75DP120RHHR serves as a functional substitute within the same series, offering DisplayPort 1:1 dual-mode repeater capabilities. Verify pin-to-pin compatibility and electrical specifications before substitution.
