TUSB544RNQT

Overview

The TUSB544RNQT is a USB Type-C multi-protocol linear redriver manufactured by Texas Instruments. It supports data rates up to 8.1 Gb/s and operates within a supply voltage range of 3 V to 3.6 V, with a typical operating voltage of 3.3 V. The device features four channels and is housed in a WQFN-40 package suitable for surface mount installation. It functions as a signal buffer and repeater for interface applications, supporting Super Speed operation standards.

Feature Summary

Supports multi-protocol operation including USB 3.1 and DisplayPort Alt Mode
Provides bidirectional linear redriver functionality for signal integrity
Configurable via I2C interface or GPIO pins for custom alternate modes

Applications

USB Type-C cable adapters and docks
DisplayPort to USB-C conversion hubs
Custom high-speed serial link implementations

Procurement Notes

Verify the specific suffix 'RNQT' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and voltage levels before integration into the design.

Selection Notes

Select this component when designing systems requiring support for both USB 3.1 and DisplayPort Alt Mode signals on a single Type-C connector. Consider the WQFN-40 package constraints and the need for I2C or GPIO configuration logic if using custom alternate modes without an external MCU.

Part Context

This part belongs to the TUSB544 series of USB Type-C linear redrivers. It is designed to extend the reach of high-speed differential signals in compact mobile and desktop interfaces. The device integrates necessary equalization to maintain signal quality across standard cable lengths.

Replacement Considerations

The TUSB542 serves as a related alternative offering 5 Gbps capability with a 2:1 MUX structure. For higher speed requirements, the TUSB1044 provides 10 Gbps multi-protocol support. Verify pinout and configuration logic compatibility when substituting.
