SN75DP119RHHT

Overview

The SN75DP119RHHT is a DisplayPort signal repeater and conditioner manufactured by Texas Instruments. It functions as a 1:1 signal repeater designed to extend the reach of DisplayPort links by regenerating and retiming signals. The device supports high-speed serial data transmission with a maximum clock frequency of 270 MHz, accommodating DisplayPort link rates up to 8.1 Gbps per lane. It operates within a supply voltage range of 3.0 V to 3.6 V and draws a typical operating current of 110 mA. The component is housed in a WQFN-40 package and is rated for an industrial temperature range from 0°C to +85°C.

Feature Summary

• Provides signal regeneration and retiming for DisplayPort links to extend cable length capabilities
• Integrates equalization circuitry to compensate for channel loss and signal degradation
• Supports hot-plug detection and auxiliary channel communication for system management

Applications

• Extending DisplayPort connections between source devices and displays beyond standard cable limits
• Signal conditioning in docking stations and display adapters
• Retiming signals in complex video distribution systems requiring multiple connection points

Procurement Notes

Verify the specific suffix RHHT against the manufacturer's official datasheet to confirm pinout compatibility and packaging details. Ensure that the procurement source provides genuine components with traceable lot codes. Check for RoHS compliance documentation if required for your assembly process. Confirm that the supplier offers appropriate handling procedures for moisture-sensitive devices.

Selection Notes

Select this component when a single-stage signal extension is required for DisplayPort interfaces. Compare performance metrics such as jitter tolerance and eye diagram closure against alternative repeaters if longer distances are needed. Consider the power consumption profile relative to system thermal constraints. Verify that the input/output voltage levels match the source and sink device specifications.

Part Context

This part belongs to the SN75DP11x series of DisplayPort interface ICs from Texas Instruments. It is functionally similar to the SN75DP119RGYR and SN75DP118, differing primarily in package type or minor electrical characteristics. The SN75DP119 series is designed specifically for DisplayPort applications, offering a compact solution for signal integrity issues in video transmission paths.

Replacement Considerations

The SN75DP119RGYR is a documented equivalent variant within the same family. Verify pin-to-pin compatibility before substitution. Other models like the SN75DP118 may offer similar functionality but require verification of specific electrical parameters and package dimensions.
