TUSB1146RNQR

Overview

The TUSB1146RNQR is a USB Type-C Alt Mode linear redriver and crosspoint switch manufactured by Texas Instruments. It supports USB 3.2 data rates up to 10 Gbps and DisplayPort 2.0 UHBR10 at 10 Gbps. The device utilizes fifth-generation USB redriver technology with adaptive equalization for DFP configurations C, D, and E. It operates on a single 3.3-V power supply and features four-level input pins for controlling equalization gain and operational modes.

Feature Summary

• Supports USB 3.1 Gen1/Gen2 and DisplayPort Alt Mode over USB Type-C
• Integrates adaptive equalization to compensate for signal loss
• Includes intelligent LFPS detection for automatic power state management

Applications

• VESA DisplayPort Alt Mode on USB Type-C downstream ports
• USB 3.1 Gen1/Gen2 signal extension in host devices
• Portable computing equipment requiring high-speed display output

Procurement Notes

Verify the specific suffix 'RNQR' against the official datasheet to confirm package type and temperature range. Ensure the component meets AEC-Q100 requirements if automotive qualification is necessary. Confirm RoHS compliance status through the manufacturer's documentation before procurement.

Selection Notes

Select this component for applications requiring 10-Gbps signal integrity over PCB traces or cables. Evaluate the need for adaptive equalization based on channel loss characteristics. Compare power consumption and thermal performance against alternative redrivers for space-constrained designs.

Part Context

This part belongs to the TUSB1146 family of USB Type-C Alt Mode redrivers. It is designed to replace passive copper cables or active repeaters in high-speed interface chains. The device simplifies design by integrating switching and equalization functions into a single compact package.
