4 Setup
This section describes the various EVM features and how to test these features. Schematic screen shots,
pictures, and block diagrams are provided as necessary.
4.1 Switch, Push Button, Connector, and Test Point Descriptions
Components described in this section are listed with respect to the EVM from left to right and top to bottom.
Related components are listed simultaneously.
4.1.1 Power Path Jumper Configuration
Out of the box, the TPS65994 EVM has jumper configuration for a TPS65994 device. With this configuration, the
two internal power paths are configured as Source paths for their respective USB Type-C ports. The two external
power paths are configured as Sink paths for their respective USB Type-C ports. When using the TPS65994
EVM, use a TPS65994 template in the TPS65994 Application Customization Tool.

4.1.2 Expansion Ports
J7 and J8 are the connectors for 10G-EXPANSION-EVM Source Board for port A and B respectively. Connect
10G-EXPANSION-EVM Source Board to evaluate DisplayPort and USB 3.2 Data. Both ports can support DP at
the same time.
Note
TPS65994 can only support DP_DFP mode. TPS65994 EVM will work with 10G-EXPANSION-EVM
Source Board only.
4.1.3 ADCINx Settings
4.1.3.1 S1 and S2: ADCIN1 and ADCIN2
The TPS65994 EVM has a switch (S1) that can be used to configure the ADCIN1 and ADCIN2 pin strapping
settings of the TPS65994. ADCIN1 is controlled through S1 and ADCIN2 is controlled through S2. Refer to
TPS65994 datasheet to see different ADCINx configurations.
Table 4-1 highlights the switch settings to enable
the different ADCINx configurations. With all switches on S1 and S2 disabled, switches S4A and S4B can be
used to directly short the ADCINx pin to LDO_1V5. The schematic for the ADCIN1 and ADCIN2 configuration
switches can be seen in
Figure 4-2 .
