TUSB211ARWBTQ1

Overview

The TUSB211ARWBTQ1 is an automotive-grade USB 2.0 high-speed signal conditioner designed to compensate for AC and DC transmission channel losses. It supports data rates up to 480 Mbps with a supply voltage range of 2.3 V to 6.5 V. The device operates within a temperature range of -40°C to +105°C and draws a typical active current of 36 mA. It features four selectable equalization levels configured via external pull-down resistors on the EQ pin, enabling support for cable lengths up to 5 meters or cascaded setups for longer distances.

Feature Summary

• Compensates for inter-symbol interference (ISI) jitter using edge boost and DC boost functions without altering packet timing or adding propagation delay.
• Supports daisy-chaining of up to four devices to extend signal integrity in high-loss transmission paths.
• Maintains signal transparency for low-speed and full-speed modes while providing automatic detection and compensation for high-speed signaling.
• Compatible with USB On-The-Go (OTG) and Battery Charging (BC) protocols.

Applications

• Automotive infotainment systems
• Automotive instrument clusters
• Active cables and cable extenders
• Backplane connections

Procurement Notes

Verify the specific ordering suffix 'RWBTQ1' corresponds to the X2QFN-12 package with a 250-unit reel quantity. Confirm that the component meets AEC-Q100 Grade 2 requirements for the intended operating temperature range. Ensure the design accounts for the moisture sensitivity level and reflow profile specified in the packaging information.

Selection Notes

Select this component when USB 2.0 high-speed signal degradation requires compensation over PCB traces or cables exceeding standard length limits. The wide supply voltage range allows flexibility in system power architectures. Use the external EQ resistor network to tune signal gain based on specific channel loss characteristics and compliance testing results.

Part Context

This part belongs to the TUSB211A-Q1 family of automotive USB redrivers. It is pin-compatible with other members of the series such as the TUSB211, TUSB212, TUSB214, TUSB216, and TUSB217A, facilitating design scalability across different voltage and performance requirements within the same platform.

Replacement Considerations

Pin-compatible alternatives include TUSB211ARWBRQ1, TUSB212QRWBTQ1, TUSB214QRWBTQ1, TUSB216QRWBTQ1, and TUSB217ARWBTQ1. Verify that the substitute part matches the required supply voltage range and thermal specifications before implementation.

FAQ

How is the signal equalization level configured?

The equalization level is set by connecting an external pull-down resistor to the EQ pin. Four distinct levels are available, ranging from 0Ω to open circuit, which determine the strength of the edge and DC boost.

Does the device affect Low-Speed or Full-Speed signals?

No, the TUSB211ARWBTQ1 is designed to be transparent to Low-Speed and Full-Speed signals. It automatically detects the connection speed and only enables signal compensation for High-Speed mode.

What is the maximum number of devices that can be cascaded?

Up to four TUSB211A-Q1 devices can be daisy-chained to compensate for signal loss in applications requiring extended cable lengths or high-loss transmission paths.
