TUSB522PRGET

Overview

The TUSB522PRGET is a dual-channel USB 3.1 redriver manufactured by Texas Instruments, designed to extend signal reach in high-speed serial links. It supports Super Speed data rates up to 5 Gbps and operates within a supply voltage range of 3 V to 3.6 V. The device draws approximately 98 mA of operating current and functions reliably across an ambient temperature range of 0°C to 70°C. Packaged in a compact 24-VQFN (4x4) format with exposed pad for thermal dissipation, it integrates input equalization and output de-emphasis capabilities to maintain signal integrity.

Feature Summary

• Provides dual-channel signal regeneration for USB 3.1 interfaces
• Integrates adaptive input equalization to compensate for channel loss
• Includes programmable output de-emphasis to optimize eye diagrams
• Supports differential signaling inputs and outputs

Applications

• USB 3.1 host and device port extensions
• Signal integrity restoration on PCB traces exceeding recommended lengths
• High-speed peripheral connectivity modules

Procurement Notes

Verify the specific suffix 'GET' against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding the 24-VQFN footprint and thermal pad requirements. Confirm moisture sensitivity level handling procedures during assembly to prevent package damage.

Selection Notes

Select this component when extending USB 3.1 signals over moderate PCB distances without requiring full retiming. Compare power consumption and thermal performance against alternatives like the SN65LVPE502 series if lower current draw or wider industrial temperature ranges are required. Verify that the 0°C to 70°C operating range meets the target application environment.

Part Context

This part belongs to the TUSB522P family of fourth-generation dual-channel USB 3.0/3.1 redrivers. It serves as a successor to earlier generations such as the HPA02286, offering improved signal conditioning features. The device complements other interface solutions by providing passive-like signal extension with active equalization benefits.

Replacement Considerations

The TUSB522PRGER is a pin-compatible alternative within the same family, differing primarily in packaging quantity rather than function. Direct substitutes from other manufacturers require careful evaluation of electrical parameters and pin definitions.
