TUSB211IRWBR

Specialized Overview

The TUSB211IRWBR is a USB high-speed signal conditioner manufactured by Texas Instruments, designed to compensate for intersymbol 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 typical power consumption of 55 mW. It features programmable signal gain selectable via external resistors to optimize performance for specific channel conditions. The component is housed in a compact 1.6 mm x 1.6 mm X2QFN-12 package suitable for surface mount applications.

Specialized Feature Summary

• Compensates for AC and DC losses caused by capacitive and resistive loads in transmission channels
• Accelerates USB 2.0 High Speed signal transition edges using edge boosters and DC boost functions
• Provides pre-equalization to mitigate jitter from intersymbol interference in long cable applications
• Maintains zero risk to DP/DM signal path continuity without introducing propagation delay or altering packet timing

Specialized Applications

• Tablets and mobile phones requiring signal integrity maintenance
• Television sets and portable electronics with extended USB connections
• Cable extenders and docking stations utilizing high-speed data transfer

Specialized Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to ensure correct packaging and temperature grade specifications. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to procurement. Cross-reference the part number with official Texas Instruments documentation to validate availability and lifecycle status.

Specialized Selection Notes

Select this component when designing systems that require compensation for signal degradation in USB 2.0 High Speed channels. Ensure the design accommodates external pull-down resistors for gain configuration if programmability is required. Verify that the operating voltage range of 3 V to 3.6 V aligns with the system power architecture and that the thermal environment stays within the -40°C to +85°C operational limits.
