Page 2: Introduction
1 Introduction The TCA39306 EVM allows the user's to test the device under different loading conditions using selectable pull-up resistors and loading capacitance. The EVM comes with U1 (DCU package) populated, but supports the use of the DDF and DTM package. Performance should be similar to DCU package, but the user may want to test different packages over temperature due to different temperature coefficents. -
Page 3: Load Capacitance Selector
Figure 2-2. Load capacitor selector The TCA39306 EVM provides a way for the designer to test the device under capacitive loading which is one of the main constraints in an I C system. -
Page 4: Dut Locations
Concept www.ti.com 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. - Page 5 If the DTM package is required to be populated, U1 must be unpopulated to reveal the location of U3. Figure 2-6 shows the location of U3. Figure 2-6. U3 Location SCPU045 – JUNE 2021 TCA39306 EVM User's Guide Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated...
