Overview
The TUSB2E111YCGR is a USB 2.0-eUSB2 repeater supporting host and device modes with low-speed, full-speed, and high-speed signaling. It operates on VDD3V3 (3.0V to 3.6V) and VDD1V8 (1.62V to 1.98V). The device features a 15-pin DSBGA package measuring 1.75mm x 1.05mm. It supports eUSB2 trace loss compensation up to 10 inches and USB channel ESR up to 20Ω via strap-pins or I2C. High-speed total jitter is 20ps. It includes BC 1.2 support, CTA-936 UART mode, and auto-resume ECR.
Feature Summary
- Supports USB 2.0 and eUSB2 (rev 1.2) standards with LS, FS, and HS signaling
- Provides configurable eUSB2 trace length compensation for various product form-factors
- Includes optional battery charging detection and advertising capabilities
- Features GPIO pins for interrupt output, debug monitoring, and I2C-to-GPIO bridging
Applications
- Notebooks and desktops
- Cell phones
- Tablets
- Wearables
- Portable electronics
Procurement Notes
Verify the specific B1 version marking T2E111A against the datasheet device variant table. Confirm the 1.8V I/O voltage requirement for the I2C bus and GPIOs matches the system design. Ensure the 15-pin WCSP YCG package dimensions are compatible with the PCB layout constraints.
Selection Notes
Select this part when an eUSB2 PHY requires connection to legacy USB 2.0 ports. Choose the B1 variant specifically for systems requiring 1.8V I/O levels. Consider the non-I2C strap-pin configuration if the host lacks an I2C interface, utilizing the three available pins for channel compensation settings.
Part Context
This component belongs to the TUSB2E11 family of USB 2.0-eUSB2 repeaters. The TUSB2E111YCGR is distinguished by its B1 silicon version and 1.8V I/O interface. It complements other variants like the TUSB2E112YCGR which utilizes a 1.2V I/O standard, allowing designers to match different SoC voltage domains.
Replacement Considerations
The TUSB2E112YCGR serves as a direct functional alternative within the same package but operates with a 1.2V I/O interface instead of 1.8V. Verify that the target system's I2C and GPIO voltages align with the replacement's specifications before substitution.
