TUSB564RNQR

Overview

The TUSB564RNQR is a USB Type-C DP Alt Mode linear redriver and crosspoint switch manufactured by Texas Instruments. It supports SuperSpeed (SS) data rates up to 5 Gb/s for USB 3.1 compliance and DisplayPort Alternate Mode at 8.1 Gbps (HBR3). The device operates on a single 3 V to 3.6 V power supply within an industrial temperature range of -40°C to +85°C. It utilizes a WQFN-40 package with SMD/SMT mounting style and features I2C interface configuration capabilities.

Feature Summary

• Supports USB 3.1 SuperSpeed and DisplayPort Alternate Mode HBR3 data transmission
• Integrates linear redriver with equalization to compensate for signal loss
• Configurable via I2C or GPIO interfaces for flexible system integration

Applications

• USB Type-C host and device port implementations
• DisplayPort alternate mode signal routing
• High-speed peripheral connectivity hubs

Procurement Notes
