TUSB2E22RZAR

Overview

The TUSB2E22RZAR is a dual eUSB2 to USB 2.0 repeater manufactured by Texas Instruments, designed to enable USB 2.0 compliance ports on processors utilizing lower voltage processes. It supports Low Speed (LS), Full Speed (FS), and High Speed (HS) signaling across two independent channels. The device operates with a VDD3V3 supply ranging from 3.0 V to 3.6 V and a VDD1V8 analog supply between 1.62 V and 1.98 V. It functions within an operating temperature range of -20°C to +85°C. The component is housed in a 20-pin VQFN package measuring 3.5 mm x 3.5 mm.

Feature Summary

• Supports dual independent repeaters with host and device mode capabilities
• Includes internal crossbar switch for flexible port mapping
• Provides four levels of eUSB2 channel loss compensation settings

Applications

• Communications equipment
• Enterprise systems
• Notebooks and desktops
• Industrial applications
• Tablets and portable electronics

Procurement Notes

Verify the specific RZA ordering suffix corresponds to the 20-pin VQFN package variant when sourcing components. Confirm that the revision level matches the required eUSB2 specification version, as earlier revisions may support different interface standards than later updates.

Selection Notes

Select this component when integrating eUSB2 interfaces into standard USB 2.0 connectors. Ensure the system design accommodates the required 3.3 V and 1.8 V power rails. Verify that the PCB layout supports the thermal requirements of the VQFN package for the intended operating environment.

Part Context

This part belongs to the TUSB2E22 series of USB interface integrated circuits. The RZA suffix specifically denotes the 20-pin VQFN package option, distinct from other available packages like the DSBGA. It serves as a bridge between embedded USB implementations and standard external connectivity.
