Overview
The TUSB1044IRNQR is a USB Type-C multi-protocol bidirectional linear redriver switch manufactured by Texas Instruments. It supports data rates up to 10 Gbps and operates within an industrial temperature range of -40°C to 85°C. The device utilizes a 40-pin WQFN package with dimensions of 6 mm x 4 mm and a 0.4 mm pin pitch. It functions as a protocol-agnostic signal conditioner, supporting USB 3.2 Gen 2 x2 and DisplayPort 2.1 alternate modes. Powered by a single 3V to 3.6V supply, it provides multiple levels of receive linear equalization to compensate for inter-symbol interference caused by cable and PCB trace losses.
Feature Summary
- Protocol-agnostic bidirectional four-channel linear redriver capable of supporting USB Type-C and DisplayPort alternate modes
- Configurable receive linear equalization to mitigate signal degradation from transmission medium losses
- Flexible configuration interface allowing channel direction and equalization control via GPIO or I2C
- Integrated advanced power management features including USB power state monitoring and DisplayPort link training listening
Applications
- Tablets
- Laptops
- Desktop computers
- Docking stations
Procurement Notes
Verify the specific suffix IRNQR confirms the industrial temperature grade (-40°C to 85°C) and the 40-WQFN package variant. Confirm RoHS compliance status against current manufacturer documentation. Ensure the ordering part number matches the required tape-and-reel packaging format for automated assembly processes.
Selection Notes
Select this component when designing systems requiring high-speed signal integrity correction for USB Type-C interfaces operating at 10 Gbps. The industrial temperature rating makes it suitable for demanding environments compared to commercial variants. Consider the I2C and GPIO control options for system integration flexibility regarding channel directionality and equalization settings.
Part Context
This device belongs to the TUSB1044 family of USB Type-C linear redrivers. It serves as a signal conditioning solution for high-speed differential pairs in modern computing platforms. The component addresses signal attenuation issues inherent in long cables and complex motherboard layouts, ensuring reliable data transmission for next-generation connectivity standards.
Replacement Considerations
The TUSB1042IRNQR is a related two-channel variant within the same product family. Verify channel count requirements before substitution, as the TUSB1042 offers only two reversible channels compared to the four channels in the TUSB1044.
