TUSB217AIRWBT

Specialized Overview

The TUSB217AIRWBT is a USB 2.0 high-speed signal conditioner designed to compensate for AC and DC losses in transmission channels. 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 36 mA of operating current and functions between -40°C and +85°C. Packaged in an X2QFN-12 format, it includes integrated ESD protection rated at 2 kV.

Specialized Feature Summary

• Compensates for channel losses using edge boosting and DC boosting to accelerate signal transitions and improve static levels.
• Supports cable lengths up to 5 meters through pre-equalization that mitigates intersymbol interference jitter.
• Integrates BC 1.2 battery charging controllers for CDP and DCP ports, enabling dynamic configuration via control pins.
• Maintains compatibility with USB 2.0, OTG 2.0, and BC 1.2 standards while remaining host/device agnostic.

Specialized Applications

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

Specialized Procurement Notes

Verify the specific suffix 'RWB' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the X2QFN-12 package dimensions align with your PCB footprint design constraints before finalizing procurement.

Specialized Selection Notes

Select this component when system designs require signal integrity restoration for USB 2.0 High Speed links over extended copper traces or cables. It is suitable for applications needing integrated battery charging detection without external logic. Consider daisy-chaining multiple units if cable lengths exceed 5 meters to support up to 10 meters total distance.

Specialized Part Context

This part belongs to the TUSB217A series of USB redrivers from Texas Instruments. It serves as a signal conditioning solution for maintaining eye diagram compliance in high-loss environments. The device is pin-compatible with earlier models like the TUSB211/212/214/216, facilitating upgrades in existing designs.

Specialized Replacement Considerations

The TUSB217AIRWBT is pin-compatible with the TUSB211, TUSB212, TUSB214, and TUSB216 series. Verify functional equivalence regarding signal enhancement settings and battery charging controller integration when substituting these parts.
