SN75DP126SSRHUR

Specialized Overview

The SN75DP126SSRHUR is a DisplayPort 1:2 re-driver switch manufactured by Texas Instruments, housed in a 56-pin WQFN package. It operates at a fixed supply voltage of 3.3 V with a maximum operating current of 138 mA. The device supports DP v1.1a/v1.2 signaling, including HBR2 data rates up to 5.4 Gbps, and TMDS clock frequencies up to 340 MHz for HDMI 1.4b compatibility. It functions within an ambient temperature range of 0°C to +85°C and provides 2kV ESD protection.

Specialized Feature Summary

• Integrates a TMDS converter to switch dual-mode DisplayPort inputs to either DP++ or HDMI/DVI-compatible outputs
• Supports automatic configuration via link training and identifies HDMI/DVI receiver types through DDC access
• Features adjustable output signal swing and pre-equalization to maintain signal integrity across varying cable lengths

Specialized Applications

• Laptop docking stations
• Desktop computer video adapters
• Computer expansion docks
• Discrete graphics card interfaces

Specialized Procurement Notes

Verify the specific suffix SSRHUR against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure compliance with RoHS directives and moisture sensitivity levels before integration into the final assembly process.

Specialized Selection Notes

Select this component when a single DisplayPort source must drive two destinations while supporting conversion to HDMI or DVI standards. It is suitable for designs requiring high-speed signal retiming up to 5.4 Gbps and robust ESD protection in compact form factors.

Specialized Part Context

This part belongs to the SN75DP126 series of display interface ICs. It serves as a successor to earlier variants like the SN75DP126DSRHUR, offering updated packaging and manufacturing specifications while maintaining core functionality for multi-display connectivity solutions.

Specialized Replacement Considerations

The SN75DP126DSRHUR is identified as a discontinued alternative that may be replaced by this model. Verify pin-to-pin compatibility and electrical parameters before substituting existing inventory.
