Overview
The TUSB544RNQR is a USB Type-C multi-protocol line redriver manufactured by Texas Instruments. It supports data rates up to 8.1 Gb/s and complies with the USB 3.1 standard. The device operates within a supply voltage range of 3 V to 3.6 V, with a typical operating voltage of 3.3 V. It features an I2C interface for configuration and is housed in a WQFN-40 surface-mount package. The component functions as a linear redriver for Super Speed signals and supports operation across a temperature range from -40°C to +85°C.
Feature Summary
- Supports USB Type-C multi-protocol line redriving for high-speed data transmission
- Configurable via I2C interface for custom alternating modes without external microcontrollers
- Linear redriver architecture designed for Super Speed signal integrity
Applications
- USB Type-C cable adapters requiring custom alternate mode support
- System designs utilizing custom Gigabit Ethernet or DisplayPort links without PD controllers
- Super Speed signal path extension in host or device interfaces
Procurement Notes
Verify the specific ordering suffix 'RQR' against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure compatibility with the required I2C addressing scheme if configuring the device for custom alternate modes. Confirm that the design accounts for the default power-on state behavior described in the official documentation.
Selection Notes
Select this component when designing systems that require redriving Super Speed signals over USB Type-C connectors while supporting custom alternate modes. It is suitable for applications where minimizing bill-of-materials complexity is critical, as it allows GPIO-based configuration instead of relying on a dedicated MCU or PD controller for initial setup.
Part Context
This part belongs to the TUSB544 series of USB Type-C redrivers. It is distinct from muxes or repeaters, functioning specifically as a linear redriver to maintain signal quality. The RNQR suffix indicates the specific tape-and-reel packaging variant intended for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin-to-pin compatibility and electrical characteristics with any alternative components before implementation.
