The ADS794xEVM-PDK contains both the ADS794xEVM and the MMB0 motherboard; however, the
devices may be shipped unconnected or configured incorrectly. Follow these steps to verify that
ADS794xEVM-PDK kit is properly configured and connected.
Step 1. Unpack the ADS794xEVM-PDK kit.
Step 2. Set the three jumpers on the MMB0 REV D as shown in Figure 6 . Below Figure 6 , there is a
check list that explains the functionality of each jumper.
Figure 6. MMB0 Jumper Locations
Follow this check list to ensure proper operation of the MMB0 with the ADS794xEVM:
• J12 must be closed. This setting allows the external supply to power up the MMB0 and the
ADS794xEVM through J2 (6-VDC input), and regulate down to +5 V, 3.3 V, and 1.8 V.
• J13B must be closed. This configuration connects the 5-V analog power supply with the 5-V digital
power supply.
• J13A must be opened. This setting allows the 5-V analog power supply to be regulated onboard.
