Overview
The TUSB1046-DCIRNQT is a USB Type-C DP Alternate Mode linear retimer and crosspoint switch manufactured by Texas Instruments. It supports up to 10 Gbps USB 3.1 data transmission rates on the upstream port and provides four DisplayPort 1.4 channels for downstream ports with data rates reaching 8.1 Gbps. The device complies with USB Type-C Specification Revision 1.1, supporting Configuration C, D, E, and F. It operates within a commercial temperature range of 0°C to 70°C and utilizes a 40-WQFN (6x4) package.
Feature Summary
- Supports USB Type-C DP Alternate Mode with integrated linear retiming capabilities
- Provides configurable crosspoint switching for signal routing between host and peripheral interfaces
- Includes multiple receiver linear equalization levels to compensate for cable and PCB trace loss-induced intersymbol interference
Applications
- USB Type-C docking stations requiring high-speed data and video output
- DisplayPort alternate mode adapters for connecting external displays
- High-bandwidth peripheral hubs integrating USB 3.1 and video signals
Procurement Notes
Verify the complete part number including the RNQT suffix to ensure the correct tape-and-reel packaging configuration. Confirm that the commercial temperature grade (0°C to 70°C) meets the operational requirements of the target application environment. Cross-reference the datasheet revision date to ensure alignment with current design specifications.
Selection Notes
Select this component when designing systems requiring simultaneous USB 3.1 data transfer and DisplayPort 1.4 video output through a single USB Type-C connector. Ensure the board layout accounts for the 40-WQFN package thermal dissipation characteristics. Verify that the system power supply voltage falls within the specified 3V to 3.6V range for proper operation.
Part Context
This device belongs to the TUSB1046 family of USB Type-C interface controllers. It serves as a bridge between USB Type-C hosts/peripherals and DisplayPort sources, enabling flexible signal path management. The RNQT suffix indicates a specific reel quantity and tape packaging format suitable for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Texas Instruments official resources for potential pin-compatible or functionally equivalent alternatives if supply constraints arise.
