TUSB1046A-DCIRNQR

Overview

The TUSB1046A-DCIRNQR is a USB Type-C DP Alt Mode linear redriver crosspoint switch manufactured by Texas Instruments. It supports USB 3.1 data transmission rates up to 10Gbps and features four DisplayPort 1.4 channels with data rates up to 8.1Gbps (HBR3). The device supports VESA DisplayPort Alt Mode configurations C, D, E, and F based on USB Type-C Standard 1.1. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 40-WQFN package measuring 4mm x 6mm with a 0.4mm pitch.

Feature Summary

Supports USB 3.1 Gen 1/Gen 2 speeds up to 10Gbps alongside four DisplayPort lanes for Alt Mode applications
Includes linear redriver with up to 14dB equalization to compensate for signal loss in cables or PCB traces
Features automatic LFPS de-emphasis control to ensure compliance with USB 3.1 certification requirements

Applications

Tablets
Notebooks
Desktops
Docking stations

Procurement Notes

Verify the specific suffix RNQR indicates the reel packaging format when sourcing components. Confirm that the A-designation aligns with the required industrial temperature range specifications for your target application environment. Ensure compatibility with the 40-WQFN footprint during PCB layout finalization.

Selection Notes

Select this component for designs requiring protocol-independent USB Type-C connectivity with integrated signal conditioning. The built-in equalization capabilities address channel loss issues without external discrete components. Verify system power supply constraints against the specified 3V to 3.6V operating voltage range before integration.

Part Context

This part belongs to the TUSB1046 family of analog and digital crosspoint ICs designed for high-speed interface management. It serves as a bridge between host devices and peripherals, enabling flexible routing of USB and DisplayPort signals within compact form factors typical of modern portable electronics.
