1.4 Device Information

The TUSB2E221EVM is designed to support the TUSB2E221 eUSB repeater in either eUSB host or peripheral applications. Various headers are located on the EVM with prepopulated headers to support configuring the TUSB2E221.

Two LDOs are also present on the TUSB2E221EVM to generate the 3.3V and 1.8V supplies to the TUSB2E221. The TPS73633 steps down the 5V supply to 3.3V to provide power to the TUSB2E221 as well as the TPS73601. The TPS73601 uses the 3.3V supply and steps down the voltage further to 1.8V again for the TUSB2E221 supply and the I/O input voltage used for configuration.
