TUSB564RGFRQ1

Overview

The TUSB564RGFRQ1 is an automotive-grade USB Type-C crosspoint switch and linear redriver designed for upstream-facing ports (Sink). It supports USB 3.2 data rates up to 5Gbps and DisplayPort 1.4 at HBR3 speeds of 8.1Gbps. The device accommodates VESA DisplayPort Alt Mode UFP_D pin assignments C, D, and E. It provides receive linear equalization up to 11.6dB to compensate for inter-symbol interference caused by cable and board trace loss. The component operates on a single 3.3V supply and features configuration via GPIO or I2C interfaces.

Feature Summary

Supports USB 3.2 up to 5Gbps and DisplayPort 1.4 up to 8.1Gbps (HBR3) for sink-side applications
Provides linear redriver functionality with up to 11.6dB equalization to mitigate signal loss
Configurable through GPIO or I2C interfaces for flexible system integration
Compatible with VESA DisplayPort Alt Mode UFP_D pin assignments C, D, and E

Applications

Automotive infotainment systems
Rear seat entertainment units
Automotive head units

Procurement Notes

Verify the specific ordering suffix RGF corresponds to the 40-pin VQFN package variant. Confirm that the component meets AEC-Q100 Grade 2 qualification standards for the intended operating temperature range of -40°C to 105°C. Ensure compatibility with the host controller's I2C voltage levels if utilizing digital configuration over GPIO alternatives.

Selection Notes

Select this component for designs requiring a sink-side redriver for USB Type-C receptacles. It is suitable for applications needing transparent DisplayPort link training and support for multiple UFP_D pin assignments. Consider the thermal performance in the 7mm x 5mm VQFN package when designing the PCB layout for adequate heat dissipation.

Part Context

This part belongs to the TUSB564-Q1 family of automotive interface devices from Texas Instruments. It is specifically engineered to handle high-speed differential signaling within vehicle cabin electronics. The RGFRQ1 designation indicates the specific package type and automotive qualification level required for production vehicles.
