SN75DP129RHHT

Specialized Overview

The SN75DP129RHHT is a DisplayPort to TMDS translator manufactured by Texas Instruments. It converts DisplayPort signals to TMDS for display interfaces. The device operates within a supply voltage range of 3 V to 3.6 V and draws a typical operating current of 110 mA. It supports a maximum working frequency of 250 MHz. The component is housed in an HVQFN-48 package with a thermal pad. It functions across an industrial temperature range from 0°C to +85°C. The part is RoHS compliant and features moisture sensitivity classification.

Specialized Feature Summary

• Translates DisplayPort signals to TMDS format
• Supports high-speed data transmission up to 250 MHz
• Integrated thermal pad for improved heat dissipation

Specialized Applications

• DisplayPort to HDMI adapters
• Laptop and desktop monitor interfaces
• All-in-one PC display modules

Specialized Procurement Notes

Verify the specific suffix RHHT indicates the tape and reel packaging variant when ordering. Confirm the HVQFN-48 package dimensions match the PCB footprint design. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Specialized Selection Notes

Select this component when a direct translation from DisplayPort source to TMDS sink is required without switching capabilities. Compare against the SN75DP139 series if different pin counts or package types are preferred. Verify that the 3V to 3.6V supply range aligns with the system power architecture. Consider the 250 MHz frequency limit for bandwidth requirements.

Specialized Part Context

This part belongs to the SN75DP1xx family of display interface ICs from Texas Instruments. It serves as a bridge between modern DisplayPort sources and legacy TMDS-based displays. Similar parts include the SN75DP129RGZT which shares functional characteristics but may differ in packaging or reel configuration. The family focuses on simplifying display connectivity in compact electronic devices.

Specialized Replacement Considerations

The SN75DP129RGZT is a public confirmed substitute offering identical functionality in a different package variant. Verify pin-to-pin compatibility before replacement. Other family members like the SN75DP139RSBR offer similar translation but require circuit redesign due to package differences.
