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.
3.2 EVM Power Configuration
3.2.1 Power Options
As noted earlier, the TUSB2E11EVM can 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.
3.2.2 Host Mode
When the TUSB2E11EVM is connected to an eUSB2 SoC that is in host mode, it should supply 5 V VBUS on
its USB connector. A 5 V source should be connected to J11 or through a bench supply to J12. The J1 jumper
should be installed on pins 1 and 2 to route the 5 V VBUS to the USB connector.
3.2.3 Device Mode – Self Powered
When the TUSB2E11EVM is connected to an eUSB2 SoC that is in device mode, it should not supply 5 V VBUS
on its USB connector. The TUSB2E11EVM can be powered from the USB connector or it can be self powered. If
it is self powered, the jumper on J12 should be removed. A 5 V source should be connected to J11 or through a
bench supply to pin 2 of J12. The J1 jumper should be removed from pins 1 and 2.
3.2.4 Device Mode – Bus Powered
When the TUSB2E11EVM is connected to an eUSB2 SoC that is in device mode, it should not supply 5 V VBUS
on its USB connector. The TUSB2E11EVM can be powered from the USB connector or it can be self powered. If
it is bus powered, the jumper on J12 should be installed and the J1 jumper should be installed on pins 1 and 2 to
route the 5 V from the USB connector to the EVM.
