TUSB212IRWBR

Specialized Overview

The TUSB212IRWBR is a USB 2.0 High Speed Signal Conditioner manufactured by Texas Instruments, designed to compensate for signal integrity losses in transmission channels. It operates on a single 3.3 V power supply with a voltage range of 3 V to 3.6 V and draws a typical operating current of 22 mA. The device supports data rates up to 480 Mb/s and features a two-port configuration within a compact 12-X2QFN (1.6 mm x 1.6 mm) package. It functions as a redriver compatible with USB 2.0 standards, ensuring signal fidelity across high-speed connections.

Specialized Feature Summary

• Compensates for inter-symbol interference (ISI) and signal loss in USB transmission channels
• Transparent operation for Low Speed and Full Speed signals without affecting their characteristics
• Supports daisy-chaining for extended reach in high-loss application scenarios

Specialized Applications

• Extending USB cable length beyond standard electrical limits
• Signal conditioning for high-density connector interfaces
• Improving signal integrity in complex PCB routing environments

Specialized Procurement Notes

Verify the specific suffix 'IRWBR' against the manufacturer's official datasheet to confirm the industrial temperature grade (-40°C to +85°C) and reel packaging quantity. Ensure the component matches the exact pinout and RoHS compliance status documented in the latest Texas Instruments release before finalizing procurement orders.

Specialized Selection Notes

Select this component when designing systems requiring transparent signal regeneration for USB 2.0 High Speed data paths. It is suitable for applications where preserving Low Speed and Full Speed signaling while correcting High Speed degradation is critical. Consider the small X2QFN footprint for space-constrained layouts.

Specialized Part Context

This part belongs to the TUSB21x family of USB 2.0 High-Speed Signal Conditioners from Texas Instruments. It serves as a specialized interface IC focused on physical layer signal integrity rather than protocol handling. The device complements other members like the TUSB211 and TUSB214 by offering specific gain and channel configurations for diverse board designs.

Specialized Replacement Considerations

Publicly confirmed substitutes include the TUSB211IRWBR and TUSB213IRWBR. Verify functional equivalence regarding gain settings and pin compatibility before substitution.
