3.1 Default EVM Configuration

When the TUSB2E11EVM is shipped, it is configured to be either wall powered from a 5 V source connected to J11 or bus powered through the USB connector, J9. The 5 V wall power supply from CUI, Digikey# 102-3584-N, or similar can be used. Please note that if a 5 V supply is connected to J11, VBUS will be supplied on the J9 USB connector unless the jumper on J1[1, 2] is removed.

I2C mode is enabled by default on the EVM. The pullups on SDA and SCL are installed through the jumpers on J2 [1,2] and J7 [1,2]. A 1.8 V I2C master can be connected to the SDA, SCL, and GND connections at J6 and access the TUSB2E11 at address 3Eh. Also, the TUSB2E11EVM is set to repeater mode by J3 [1, 2].

All power jumpers are installed by default (J13, J14, J15, and J16). These can be removed to externally supply power or take current measurements.
