Overview
The TUSB551RWBR is a single-channel USB 3.0 re-driver manufactured by Texas Instruments, designed to restore signal integrity for high-speed serial links. It supports data rates up to 5 Gbps with a propagation delay of 278 ps and a maximum clock frequency of 2.5 GHz. The device operates on a single 1.8 V supply voltage (range 1.62 V to 1.98 V) and features input equalization and output de-emphasis capabilities. Packaged in a compact 12-X2QFN (1.6x1.6 mm) surface-mount format, it functions within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Provides analog signal conditioning through integrated input equalization and output de-emphasis to compensate for channel loss.
- Supports USB 3.0 signaling standards with low propagation delay to maintain timing integrity.
- Operates from a single 1.8 V power supply rail for simplified system design.
Applications
- Signal restoration for USB 3.0 host-to-device connections
- Board-level interconnects requiring signal integrity enhancement
- High-speed peripheral interface circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure that the procurement documentation matches the exact part number TUSB551RWBR to avoid confusion with other variants in the TUSB551 family. Cross-reference the RoHS status and moisture sensitivity level requirements with your assembly process guidelines before placing orders.
Selection Notes
Select this component when designing USB 3.0 interfaces that require signal regeneration over PCB traces or connectors. The 12-X2QFN package is suitable for space-constrained layouts. Confirm that the system power budget accommodates the 1.8 V supply requirement and that the thermal environment remains within the specified -40°C to +85°C operating range for reliable performance.
Part Context
This part belongs to the TUSB551 series of USB redrivers from Texas Instruments. It is distinct from the TUSB211, which is a USB 2.0 signal conditioner, and the TUSB320, which is a USB Type-C configuration controller. The TUSB551 is specifically engineered for SuperSpeed USB applications rather than legacy High-Speed USB protocols.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with any alternative components by comparing pinout configurations, electrical characteristics, and functional specifications against the official TUSB551 datasheet.
