TUSB501TDRFRQ1

Overview

The TUSB501TDRFRQ1 is a single-channel USB 3.0 redriver designed for automotive applications, certified to AEC-Q100 standards. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 43.8mA. The device supports data rates up to 5Gbps with a propagation delay of 290ps. It features input equalization and output de-emphasis capabilities to maintain signal integrity over lossy traces. The component is housed in an 8-WSON package measuring 2x2mm, suitable for surface-mount installation across a temperature range of -40°C to 85°C.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 specifications
• Integrated signal conditioning including input equalization and output de-emphasis
• Single-channel architecture optimized for USB 3.0 SuperSpeed data paths

Applications

• Automotive infotainment systems requiring robust USB connectivity
• Vehicle telematics units utilizing USB 3.0 interfaces
• In-car display modules needing signal restoration over PCB traces

Procurement Notes

Verify the specific suffix 'TDRFRQ1' confirms the automotive qualification and reel packaging format. Confirm that the design-in process accounts for the required external AC coupling capacitors on the transmit lines as specified in the datasheet. Ensure the PCB layout adheres to the thermal and impedance guidelines provided by Texas Instruments for the 8-WSON package to guarantee performance.

Selection Notes

Select this component when an automotive-qualified USB 3.0 redriver is required for single-lane applications. It serves as a direct replacement for standard TUSB501 variants in environments demanding extended temperature ranges and higher reliability standards. Consider the 8-WSON footprint constraints during mechanical design. Verify compatibility with the host controller's electrical characteristics before finalizing the bill of materials.

Part Context

This part belongs to the TUSB501 family of USB 3.0 redrivers from Texas Instruments. While the base TUSB501 is a general-purpose interface IC, the TDRFRQ1 variant specifically targets the automotive sector with enhanced durability certifications. It complements other TI interface solutions like the TUSB522 hub controllers in complex vehicle network topologies.

Replacement Considerations

Publicly confirmed substitute part numbers include TUSB501DRFR for non-automotive contexts. Direct automotive equivalents within the same family should be cross-referenced against the latest TI substitution guides to ensure pinout and functional compatibility.
