5.1 Device Default Configuration

Per the ADS54J60 user guide, install and launch the ADS54JXX GUI. Load the default configuration files to program the LMK (onboard clocking chip) and the ADC.

  1. Load LMK_Config_Onboard_983p04_MSPS.cfg
  2. Perform a hard reset the ADC, using the onboard pushdown
  3. Load ADS54J60_LMF_8224.cfg
    1. Can load any other desired ADC configuration file, depending on the desired mode of operation
