TUSB1146RNQT

Overview

The TUSB1146RNQT is a USB Type-C crosspoint switch and linear redriver supporting USB 3.2 data rates up to 10Gbps and DisplayPort 2.0 up to 10Gbps (UHBR10). It accommodates D_DFP pin assignments C, D, and E. The device features adaptive receiver equalization (AEQ) for USB DFP receivers and supports limited redriver options on the UFP transmitter with adjustable TX voltage swing from 800mVpp to 1100mVpp. It operates on a single 3.3V supply within commercial temperature ranges of 0°C to 70°C.

Feature Summary

Supports USB 3.2 Gen 1/Gen 2 at 10Gbps and DisplayPort 2.0 at 10Gbps
Incorporates adaptive receiver equalization to improve interoperability
Configurable via GPIO or I2C interface
Includes Intel proprietary DCI capability for closed chassis debugging

Applications

Notebooks and desktops
Tablets
Docking Stations

Procurement Notes

Verify the specific ordering suffix 'RNQT' against the manufacturer's current orderable addendum to confirm package type and reel specifications. Ensure the component matches the required commercial temperature range and that all external passive components align with the datasheet recommendations for AC coupling and pull-up resistors.

Selection Notes

Select this component when designing systems requiring VESA DisplayPort Alt Mode support for configurations C, D, and E. It is suitable for applications needing protocol-agnostic linear redriving for other Alt Modes like HDMI. Consider the adaptive equalization feature if cable and PCB trace losses vary significantly across different system designs.

Part Context

This part belongs to the TUSB1146 family of USB Type-C Alt Mode redriving switches. The RNQT suffix indicates a specific tape-and-reel packaging configuration for surface-mount assembly. It serves as a bridge between host controllers and USB Type-C receptacles, managing signal integrity for high-speed data and video transmission.
