TUSB1146IRNQT

Overview

The TUSB1146IRNQT is a USB Type-C Alt Mode Redriver/MUX supporting USB 3.2 data rates up to 10 Gbps and DisplayPort 2.0 UHBR10 at 10 Gbps. It features adaptive linear equalization for DFP configurations C, D, and E. The device operates on a single 3.3-V supply with an industrial temperature range of -40°C to +85°C. It includes four-level input pins (I2C_EN, EQ[1:0], DPEQ[1:0], SSEQ[1:0]) for gain control and mode selection via resistive dividers. The component supports USB 3.1 Gen1/Gen2 power states and manages DP channel activity through AUX snooping.

Feature Summary

Adaptive linear equalization compensates for signal loss in PCB traces and cables
Supports VESA DisplayPort Alt Mode configurations C, D, and E
Intelligent LFPS detection automatically disables equalization during low-frequency signaling
AUX traffic monitoring enables dynamic channel power management

Applications

USB Type-C downstream port host interfaces
DisplayPort Alt Mode signal integrity extension
High-speed peripheral connectivity hubs

Procurement Notes

Verify the specific suffix IRNQT against official Texas Instruments documentation to confirm the industrial temperature grade (-40°C to +85°C) and reel packaging configuration. Ensure compatibility with system voltage requirements and I2C control interface specifications before integration.

Selection Notes

Select this component when designing USB 3.2 Gen2x1 or DisplayPort 2.0 UHBR10 links requiring signal regeneration over lossy channels. The industrial temperature rating suits environments exceeding commercial limits. Confirm that the four-level input pin architecture aligns with the board's resistor network design capabilities.

Part Context

This part belongs to the TUSB1146 family of USB Type-C Alt Mode redrivers. It complements other interface solutions like the TUSB1064 and TUSB1142 by providing specialized support for DisplayPort Alt Mode alongside standard USB 3.2 data transmission within a compact WQFN package.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference material. Verify functional equivalence with TUSB1142 or TUSB1064 only if datasheet parameters match exactly.
