TUSB217ARWBR

Specialized Overview

The TUSB217ARWBR is a USB 2.0 high-speed signal conditioner manufactured by Texas Instruments, designed to compensate for AC and DC losses in transmission channels. It operates within a power supply voltage range of 2.3 V to 6.5 V and supports High Speed (HS), Full Speed (FS), and Low Speed (LS) data rates. The device is housed in an X2QFN-12 package with a maximum operating temperature of +105°C and a minimum of -40°C. It features configurable edge boosting and DC boosting settings via external resistors, along with RX equalization options to mitigate intersymbol interference.

Specialized Feature Summary

• Compensates for channel losses using patented edge boosting and DC boosting mechanisms to accelerate signal transitions and improve static levels.
• Supports USB 2.0 compliance over cable lengths up to 5 meters, or up to 10 meters when daisy-chained with another device.
• Integrates BC 1.2 battery charging controllers for dynamic configuration of CDP and DCP pins.

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 the reel packaging format as documented in distributor specifications. Confirm that the component meets AEC-Q100 automotive qualification standards if required for the target application environment. Ensure compatibility with the X2QFN-12 footprint during PCB layout planning.

Specialized Selection Notes

Select this component when signal integrity degradation due to trace capacitance or resistance is observed in USB 2.0 designs. It serves as a pin-compatible replacement for older TUSB211/212/214/216 series devices. Consider its low shutdown power consumption for battery-operated portable systems requiring efficient power management.

Specialized Part Context

This part belongs to the TUSB217A family of USB redrivers and signal conditioners. It is distinct from controller ICs like the TPS25741, focusing purely on physical layer signal restoration rather than protocol handling or power delivery negotiation.

Specialized Replacement Considerations

The datasheet confirms pin compatibility with the TUSB211, TUSB212, TUSB214, and TUSB216 series. Verify that the legacy device's performance requirements are met by the TUSB217A's enhanced equalization capabilities before substitution.
