USB 2.0 high-speed signal conditioner for portable and desktop systems
The Texas Instruments TUSB217AIRWBR is a USB 2.0 high-speed signal conditioner designed to restore signal integrity on USB traces running through cables, connectors, and long PCB routes. It targets exactly the kind of layout where the eye diagram starts closing — cell phones, tablets, laptops, and desktop motherboards where the USB path can exceed the clean reach of the raw transceiver. A wide supply range from 2.3V to 6.5V lets it run directly from USB VBUS (5V nominal) or from a lower system rail without an extra regulator. That simplifies the power tree in tight designs where every component counts against the BOM. The part comes in a 12-XFQFN package (supplier device package 12-X2QFN, 1.6x1.6 mm), a tiny footprint that fits into the cramped edge of a mobile PCB near the USB connector. Surface-mount assembly is standard; the small body means the layout engineer needs to pay attention to the pad pattern and keep-out zones to avoid solder bridging.
Active lifecycle — no obsolescence concern for new designs
The TUSB217AIRWBR carries an Active product status. For a procurement decision, this removes the last-time-buy risk and the need to qualify a drop-in replacement mid-production.
