TUSB2E2211001YCGR

Overview

The TUSB2E221 is a USB 2.0-eUSB2 dual repeater supporting low-speed, full-speed, and high-speed signaling with compliance to USB 2.0 and eUSB2 rev 1.2 standards. It features two independent repeaters for simultaneous operation and includes a 2:2 crossbar multiplexer in the DSBGA package variant. The device supports host and device modes (DRD) and offers auto-detection for I2C or strap-pin configuration options. It provides four levels of eUSB2 trace loss compensation and eight USB 2.0 channel compensation settings. Power supplies include VDD3V3 (3.0V to 3.6V) and VDD1V8 (1.62V to 1.98V), operating within a temperature range of -40°C to 85°C.

Feature Summary

Dual independent repeaters enable simultaneous connection between eUSB2 ports and USB 2.0 connectors.
Configurable via I2C interface or three strap-pins for flexible system integration without external controllers.
Supports dynamic selection between 1.2V and 1.8V control logic levels using the VIOSEL pin.
Includes patented designs for robust interoperability, optimum performance, and power efficiency.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to ensure correct package type and feature set. Confirm that the selected variant matches the required eUSB2 signaling voltage and trace length compensation levels for your specific PCB layout. Always consult the latest datasheet revision history for any changes to recommended operating conditions or thermal metrics before finalizing procurement.

Selection Notes

Select the YCG package if a 2:2 crossbar mux is required for signal routing flexibility. Choose the VBW package for standard dual-repeater configurations without cross-switching needs. Ensure the chosen variant supports the necessary frame-based low-power mode if power management is critical. Verify compatibility with the target processor's eDSPr or eUSPr interface requirements regarding signaling voltages and protocol support.

Part Context

The TUSB2E221 belongs to Texas Instruments' USB 2.0-eUSB2 repeater family, designed to bridge legacy USB 2.0 interfaces with modern lower-voltage processor technologies. It addresses the need for signal integrity in compact form factors by providing adjustable equalization and termination settings. This component facilitates the implementation of USB 2.0 compliant ports on newer processors utilizing lower voltage processes, ensuring backward compatibility and performance.
