2.2 EVM Configuration

There are many ways to configure the TUSB2E221EVM to fit various applications. The power supply cam be external or provided by VBUS. The GPIO pins and I2C interface of the TUSB2E221 allow for configuration of signal conditioning settings. I2C mode is enabled by default on the EVM through the jumpers installed on J19 and J20. To access the I2C interface, attach a 1.8V I2C controller to the SDA, SCL and GND pins on header J4. The 7-bit I2C target address is 0x4F.

Note: Rev A. of the TUSB2E221EVM has SCL and SDA reversed from what is shown in the schematic. SCL is pin 1 of J4, and SDA is pin 2.
