10 Applications and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.
10.1 Application Information
The TUSB2E221 can be used in either HOST or Peripheral implementation. The mode is configured by the
eUSB2 SoC.

10.2.1 Design Requirements
The TUSB2E221 supports the eUSB2 specification. eUSB2 SoC must be compliant to the eUSB2 specification.
10.2.2 Detailed Design Procedure
The TUSB2E221 has multiple loss compensation settings for high-speed operation so make sure the selected
settings match the system loss profile to optimize jitter performance. USB 2.0 high speed eye diagram
measurements can be used as a guide to confirm the loss compensation is optimum for a given system.
