Overview
The TUSB216RWBT is a USB 2.0 high-speed signal conditioner manufactured by Texas Instruments, designed to restore signal integrity in USB transmission channels. It operates within a supply voltage range of 2.3 V to 6.5 V and draws a typical operating current of 22 mA. The device supports data rates up to 480 Mb/s and functions reliably across an extended temperature range from -40°C to +105°C. Housed in an X2QFN-12 surface-mount package, it complies with USB 2.0 standards and includes ESD protection features.
Feature Summary
- Compensates for AC and DC losses in PCB traces to maintain signal integrity
- Provides automatic polarity correction for differential USB connections
- Supports hot-plug operations without requiring external control logic
Applications
- Extending USB trace lengths on motherboards and peripheral devices
- Signal conditioning for high-speed USB ports in industrial equipment
- Restoring signal quality in complex multi-layer PCB layouts
Procurement Notes
Verify the specific suffix 'T' indicates the reel packaging configuration when sourcing components. Confirm that the Q1 designation is absent, as this distinguishes the commercial grade from automotive qualified variants. Ensure the X2QFN-12 package dimensions match the target footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when extending USB 2.0 High Speed traces beyond standard length limitations without adding latency. Compare against the TUSB216IRWBT if a narrower industrial temperature range (-40°C to +85°C) suffices for the application. Verify power supply constraints align with the 2.3 V to 6.5 V operational window.
Part Context
This part belongs to the TUSB216 series of USB redrivers, which are optimized for maintaining signal fidelity in high-speed digital interfaces. It serves as a passive-like active repeater that requires minimal external components. The RWBT variant specifically denotes the commercial temperature grade and tape-and-reel packaging format.
Replacement Considerations
The TUSB216IRWBT offers identical electrical performance but is rated for an industrial temperature range of -40°C to +85°C. The TUSB216RWBR provides the same functionality in a cut-tape or reel format with a commercial temperature range.
