TUSB211RWBR

Specialized Overview

The TUSB211RWBR is a USB high-speed signal conditioner manufactured by Texas Instruments, designed to compensate for inter-symbol interference (ISI) and signal loss in transmission channels. It supports USB 2.0 High-Speed data rates of 480 Mb/s while remaining transparent to Low-Speed and Full-Speed signals. The device operates on a single 3.3 V power supply with a maximum voltage of 3.6 V and a minimum of 3 V. Typical operating current is 20 mA, resulting in approximately 55 mW power consumption. It is housed in a compact 12-pin X2QFN package measuring 1.6 mm x 1.6 mm. The component functions within an industrial temperature range from -40°C to +85°C.

Specialized Feature Summary

• Compensates for AC and DC losses caused by capacitive and resistive loads in USB transmission paths.
• Accelerates signal transition edges using edge boosters and improves static levels via DC boosting.
• Features programmable signal gain selectable through external pull-down resistors for precise channel optimization.
• Maintains signal path continuity without damaging DP and DM traces, ensuring zero-risk system design.

Specialized Applications

• Portable electronics such as tablets and smartphones requiring extended USB connectivity.
• Desktop and laptop computers utilizing USB hubs or docking stations.
• Television sets and cable extenders needing signal integrity restoration over long cables.
• Backplane connections in embedded systems where signal degradation is prevalent.

Specialized Procurement Notes

Verify the specific ordering suffix RWBR to confirm the X2QFN-12 package and reel packaging configuration. Confirm that the NRND status does not impact immediate production requirements. Ensure compatibility with existing PCB footprints for the 1.6mm x 1.6mm footprint. Check moisture sensitivity level handling procedures during assembly. Validate that the 3.3V supply rail meets the specified 3V to 3.6V operational window.

Specialized Selection Notes

Select this component when USB 2.0 High-Speed signal integrity requires compensation for channel loss without adding propagation delay. It is suitable for applications supporting USB OTG and Battery Charging 1.2 protocols. Consider the programmable gain feature if channel characteristics vary significantly across designs. The device is appropriate for space-constrained portable devices due to its small QFN form factor. Ensure the design environment supports the required external pull-down resistor network for gain setting.

Specialized Part Context

The TUSB211RWBR belongs to the TUSB211 series of USB redrivers and signal conditioners. It is part of Texas Instruments' third-generation USB 2.0 480Mbps conditioning solutions. This series addresses increasing demands for reliable high-speed data transfer in consumer electronics. The device complements other interface ICs by extending the effective length of USB cables and traces.

Specialized Replacement Considerations

The automotive-grade variant TUSB211QRWBRQ1 offers similar functionality with AEC-Q100 qualification. For evaluation purposes, the TUSB211RPTREVM module provides a reference platform for testing signal conditioning performance.
