TUSB1044RNQT

Overview

The TUSB1044RNQT is a bidirectional linear redriver designed for USB Type-C Alt Mode applications, supporting data rates up to 10 Gbps. It features four independent channels with configurable receive linear equalization to compensate for signal loss in cables and PCB traces. The device operates on a single 3.3 V supply (3V to 3.6V range) and includes an input capacitance of 5 pF. It supports hot-plug insertion and offers GPIO and I2C control for channel direction and equalization settings. The component is housed in a 40-WQFN package measuring 6x4 mm with an exposed pad.

Feature Summary

• Protocol-agnostic bidirectional linear redriver supporting USB Type-C Alt Mode and DisplayPort interfaces
• Configurable receive linear equalization to mitigate inter-symbol interference from cable and trace losses
• Integrated SBU signal crosspoint multiplexer for advanced port management
• Supports hot-plug operations with low power consumption via single 3.3 V supply

Applications

• Signal conditioning within USB Type-C cables
• SBU signal crosspoint multiplexing in docking stations
• High-speed interface extension in laptops and tablets

Procurement Notes

Verify the specific suffix 'RNQT' against the manufacturer's official datasheet to confirm the exact temperature grade and packaging configuration. Ensure the ordering part number matches the required commercial or industrial operating range. Confirm RoHS3 compliance status directly from the latest production documentation before procurement.

Selection Notes
