TUSB546A-DCIRNQR

Overview

The TUSB546A-DCIRNQR is a USB Type-C DP Alt Mode linear redriver and crosspoint switch manufactured by Texas Instruments. It supports Super Speed data rates up to 8.1 Gbps for multi-protocol line A applications. The device operates within an extended industrial temperature range of -40°C to +85°C. It is housed in a WQFN-40 surface-mount package designed for SMD/SMT installation. The component complies with USB-C 1.0 standards and features DFP port type connectivity. It is supplied in reel packaging, typically in quantities of 3000 units per factory roll.

Feature Summary

Provides linear redriver functionality to compensate for signal integrity degradation caused by cable or PCB trace losses.
Supports DisplayPort Alternate Mode over USB Type-C interfaces with configurable receiver linear equalization levels.
Integrates crosspoint switching capabilities to manage signal routing between upstream and downstream ports.

Applications

Enabling HDMI transmission over USB Type-C connections
Implementing DisplayPort Connectivity (DCI) solutions
Signal conditioning for high-speed USB Type-C host and device interfaces
