Overview
The TUSB1046A-DCIRNQT is a USB Type-C DisplayPort Alternate Mode linear retimer and crosspoint switch manufactured by Texas Instruments. It supports USB 3.1 data rates up to 10 Gbps and provides four channels for DisplayPort 1.4 signals with data rates up to 8.1 Gbps. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a 40-pin WQFN package measuring 6x4 mm. It accepts a supply voltage between 3V and 3.6V, features an input capacitance of 10 pF, and includes multiple receiver linear equalization levels to mitigate inter-symbol distortion caused by cable or PCB trace losses.
Feature Summary
- Supports VESA DisplayPort Alternate Mode compliant with USB Type-C Specification Revision 1.1
- Configurable as downstream-facing port (DFP) with protocol-independent operation
- Integrates adjustable linear equalization for signal integrity compensation
- Provides ESD protection rated at 15 kV HBM
Applications
- Portable computing devices requiring high-speed display output
- Docking stations facilitating USB and DisplayPort connectivity
- Industrial equipment needing robust signal transmission over long cables
- Consumer electronics supporting USB Type-C alternate modes
Procurement Notes
Verify the specific suffix 'RNQT' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 'A' designation in the part number aligns with the intended industrial temperature grade specifications for your application environment. Ensure compatibility with standard surface-mount placement equipment given the 40-WQFN form factor.
Selection Notes
Select this component when designing systems requiring simultaneous USB 3.1 and DisplayPort 1.4 signal routing through a single connector. Consider the integrated equalization capabilities if utilizing passive copper cables exceeding typical length limits. Evaluate the 40-pin footprint constraints against available board space compared to alternative retimer solutions.
Part Context
This device belongs to the TUSB1046 family of USB Type-C retimers. It serves as a bridge between host controllers and external peripherals, enabling high-bandwidth video and data transfer. The TUSB1046A variant specifically targets industrial applications, offering extended temperature tolerance compared to commercial-grade counterparts like the TUSB1046.
Replacement Considerations
The TUSB1046-DCIRNQT is a commercial-grade alternative with a 0°C to 70°C operating range. The TUSB1044 series offers multi-protocol support but lacks specific DP Alt Mode optimization. Verify pinout and electrical characteristics before substituting with other retimer ICs.
