SN75DP120RHHT

Overview

The SN75DP120RHHT is a single-port Dual-Mode DisplayPort (DP++) repeater manufactured by Texas Instruments. It regenerates the DP high-speed digital link to extend signal integrity. The device operates within a supply voltage range of 3 V to 3.6 V and supports an operating temperature range from 0°C to +85°C. It is housed in a 36-pin VQFN package measuring 6 mm by 6 mm. This component functions as a buffer and re-driver for display interfaces, ensuring reliable transmission of video data across extended cable lengths or complex routing topologies.

Feature Summary

• Regenerates DisplayPort high-speed digital links for signal integrity extension
• Supports Dual-Mode DisplayPort (DP++) functionality for single-port operation
• Integrated buffer and re-driver architecture for display interface applications

Applications

• Extending DisplayPort signal reach in desktop and laptop systems
• Dual-Mode DisplayPort (DP++) signal regeneration in multimedia devices
• High-speed digital link buffering in professional display equipment

Procurement Notes

Verify the specific suffix RHHT corresponds to the 36-pin VQFN (6x6) package variant when sourcing. Confirm that the procurement channel provides official datasheets matching the SN75DP120 series specifications. Ensure compatibility with the required 3V to 3.6V supply voltage and industrial temperature range for the intended application environment before finalizing orders.

Selection Notes

Select this component when a single-port solution is required to regenerate both DisplayPort and Dual-Mode signals simultaneously. It is suitable for designs needing to overcome trace loss or cable attenuation in display chains. Consider the 36-pin VQFN footprint for PCB layout constraints. Verify that the system design accommodates the specified operating voltage and thermal requirements for stable performance.

Part Context

This part belongs to the Texas Instruments SN75DP120 series of display interface integrated circuits. It is categorized under signal buffers, repeaters, and splitters. The series focuses on maintaining signal quality for high-bandwidth video interfaces. Related components in the family may include variants with different packaging or pin configurations, but all share the core function of DisplayPort link regeneration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official replacement guide or contact technical support directly for validated alternatives. Do not assume cross-compatibility with other DisplayPort repeaters without verifying electrical and mechanical specifications.
