TUSB521RGFRQ1

Overview

The TUSB521RGFRQ1 is an automotive-grade USB 3.0 signal repeater manufactured by Texas Instruments, designed to extend the reach of high-speed data links in vehicle networks. It supports SuperSpeed data rates up to 5 Gbps while maintaining signal integrity over extended cable lengths. The device operates within a supply voltage range of 3.0 V to 3.6 V and functions reliably across an industrial temperature range from -40°C to +125°C. Packaged in a compact 28-pin VQFN (RGFR) format with exposed thermal pad, it integrates I2C control interface for configuration management.

Feature Summary

• Supports USB 3.0 SuperSpeed data transmission with automatic polarity correction
• Integrates I2C serial interface for dynamic configuration and status monitoring
• Provides robust signal conditioning to maintain link reliability in electrically noisy automotive environments

Applications

• Automotive infotainment systems requiring long-distance USB connectivity
• Vehicle sensor interfaces extending data acquisition ranges
• In-vehicle network hubs connecting peripheral devices

Procurement Notes

Verify AEC-Q100 qualification status and specific tape-and-reel packaging quantities directly with authorized distributors. Confirm RoHS compliance documentation matches current regulatory requirements. Ensure ordering suffixes align with exact package variant and temperature grade specifications before finalizing procurement orders.

Selection Notes

Select this component when designing automotive USB 3.0 topologies requiring signal regeneration beyond standard cable limits. Evaluate power consumption constraints against the 3.0 V to 3.6 V operating range. Consider thermal dissipation requirements due to the exposed pad design in dense PCB layouts.
