2.4 DUT locations
The TCA39306EVM comes populated with U1 as the DUT (Device Under Test) which is the TCA39306 in the
DCU package seen in the
Figure 2-3 . The EVM includes the DDF package and the DTM package unpopulated.
Figure 2-3. U1 location
If the user would prefer to use the DDF package, then U1 would need to be removed and U2 can then be
populated. In additional to populating U2, the resistors: R11, R12, R17, R19, R22, R20, and R23 all must be
populated with 0 Ω resistors. These resistors can be found on the back of the EVM and shown in
Figure 2-4 .
