TUSB522PRGER

Overview

The TUSB522PRGER is a dual-channel USB 3.1 redriver manufactured by Texas Instruments, designed to restore signal integrity for Super Speed data transmission. It operates within a supply voltage range of 3 V to 3.6 V and draws approximately 92 mA to 98 mA of operating current. The device supports data rates up to 5 Gb/s and functions reliably across an industrial temperature range of -40°C to +85°C. Packaged in a compact 24-pin VQFN (4x4 mm) format with exposed pad, it integrates input equalization and output de-emphasis capabilities to compensate for channel loss.

Feature Summary

• Dual-channel architecture supporting simultaneous high-speed data paths
• Integrated signal conditioning with input equalization and output de-emphasis
• Compatible with USB 3.1 Super Speed standards

Applications

• High-performance computing systems requiring reliable USB connectivity
• Peripheral docking stations and hubs
• Industrial equipment with extended temperature requirements

Procurement Notes

Verify the specific suffix 'GER' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS3 directives and check Moisture Sensitivity Level (MSL) ratings prior to PCB assembly processing. Confirm that the intended application environment falls within the specified -40°C to +85°C operational temperature range.

Selection Notes

Select this component when designing circuits requiring active signal restoration for USB 3.0 or 3.1 links over lossy traces. Compare power consumption figures against system thermal constraints, noting the typical operating current near 92-98 mA. Evaluate the 24-VQFN footprint availability against existing board layout constraints and ensure adequate thermal relief via the exposed pad for heat dissipation.

Part Context

This part belongs to the TUSB522P series of USB redrivers from Texas Instruments. It serves as a fourth-generation solution for maintaining signal quality in high-speed interfaces. Related components in the family include variants like the TUSB522PRGET, which may differ in packaging or reel configuration but share core functional characteristics.

Replacement Considerations

The SN65LVPE502CPRGER is a documented alternative within the same product category. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Note that legacy parts such as the HPA02286ARLL are discontinued and should not be used for new designs.
