TUSB2E112YCGT

Overview

The TUSB2E112YCGT is a USB 2.0 to eUSB2 repeater manufactured by Texas Instruments, designed for systems requiring signal conversion between legacy USB 2.0 ports and modern eUSB2 PHYs. It supports low-speed, full-speed, and high-speed signaling with a best-in-class total jitter of 20ps. The device operates on a 3.3V supply (VDD3V3) and an analog supply of 1.8V (VDD1V8), with a recommended operating temperature range from -20°C to 85°C. It features a 15-pin DSBGA package and includes configurable strap-pins or an I2C interface for channel compensation settings up to 20Ω ESR.

Feature Summary

• Supports dual-role device functionality for both host and peripheral modes
• Provides flexible configuration via three strap-pins or an I2C interface for fine-tuning RX equalization and TX parameters
• Includes optional battery charging detection supporting BC 1.2 CDP and DCP modes
• Offers debug capabilities through GPIO pins configured for interrupt monitoring or CTA-936 UART mode

Applications

• Notebooks and desktop computers
• Cell phones and tablets
• Wearable electronics
• Portable electronic devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout and voltage compatibility. Ensure the selected variant matches the required I/O voltage levels for the target system's I2C and GPIO interfaces. Confirm package availability and lead times directly with authorized distributors prior to finalizing procurement plans.

Selection Notes

Select the TUSB2E112YCGT when a 1.2V I/O voltage level is required for the I2C bus and GPIO connections. Compare register defaults against other variants like the TUSB2E111 if auto-resume ECR support is necessary. Evaluate the need for I2C configuration versus strap-pin setup based on system complexity and available microcontroller resources.

Part Context

This component belongs to the TUSB2E11 series of USB-to-eUSB2 repeaters. It shares core architectural features with other variants in the family but differs in specific I/O voltage configurations and default register settings. The series is designed to bridge the gap between older USB standards and newer embedded USB implementations in compact form factors.

Replacement Considerations

Direct replacements within the same family include the TUSB2E111YCGR, which utilizes a 1.8V I/O voltage instead of 1.2V. Verify that the substitute part number supports the required auto-resume ECR feature if applicable. Ensure the replacement maintains compatibility with the existing PCB layout and power supply constraints.
