TUSB217AIRWBR

Specialized Overview

The TUSB217AIRWBR is a USB 2.0 high-speed signal conditioner manufactured by Texas Instruments, designed to compensate for transmission channel losses caused by capacitive and resistive effects. It operates within a supply voltage range of 2.3 V to 6.5 V, with a typical operating voltage of 5 V. The device supports data rates up to 480 Mb/s, covering Low Speed (LS), Full Speed (FS), and High Speed (HS) modes. It draws 22 mA during operation and functions reliably across an extended temperature range from -40°C to +85°C. Housed in an X2QFN-12 surface-mount package, it integrates BC 1.2 charging controllers and offers configurable signal enhancement settings.

Specialized Feature Summary

• Compensates for AC and DC transmission losses using edge boosting and DC boosting technologies to maintain signal integrity over long cables.
• Integrates Battery Charging 1.2 (BC 1.2) controllers for CDP and DCP ports, enabling dynamic port configuration via control pins.
• Supports cable lengths up to 5 meters with a single unit or up to 10 meters when daisy-chained, ensuring compliance with USB 2.0 eye diagrams.
• Features configurable RX equalization to mitigate inter-symbol interference (ISI) jitter in high-loss applications.

Specialized Applications

• Laptops and desktop computers
• Portable electronic devices and tablets
• Active cables and cable extenders

Specialized Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the component meets RoHS standards and humidity sensitivity requirements for your assembly process. Cross-reference the manufacturer part number with official datasheets to ensure compatibility with existing PCB layouts and design-in documentation.

Specialized Selection Notes

Select this component when extending USB 2.0 connections beyond standard cable limits without requiring active protocol conversion. It is suitable for host/device agnostic designs where low power consumption during disconnect states is critical. Ensure the application environment stays within the specified -40°C to +85°C operational temperature range.

Specialized Part Context

This device belongs to the TUSB217A series of USB redrivers. It is pin-compatible with earlier generations such as the TUSB211, TUSB212, TUSB214, and TUSB216, facilitating easier upgrades in existing designs. The series focuses on passive signal conditioning rather than active protocol bridging.

Specialized Replacement Considerations

Direct pin-compatible replacements include other variants within the TUSB217A family, such as TUSB217AIRGTR. Verify package type and suffix differences before substitution to ensure mechanical and electrical compatibility.
