The configuration example of DAC39RF20EVM in JMODE 0, (bypass mode) is shown below.

1. JMODE 0 is considered bypass mode or real data mode, interpolate x1.
   1. Configuration details:
      1. 20GSPS at +6dBm
      2. 20.625Gbps SERDES rate
      3. 16 lanes
      4. JESD_M = 1
2. Follow the steps in the following figures to launch the DAC GUI. Following the steps as shown to configure the EVM.
