4.3 Complex Decimation Mode
The following software configuration steps will program the ADC364xEVM in Complex Decimation mode (16x)
with a 10 MHz analog input and 9.9 MHz NCO.
4.3.1 ADC35XX GUI: Complex Decimation Configuration
After launching the ADC35xxEVM GUI perform the following steps:
• Under Resolution, select 14 bit.
• Under DDC, Select Complex.
• For Decimation Factor, select 16.
• For Fs(MHz), select 60M.
• Under "FNCO A (MHz)", enter "9.9" in the field. This field will then calculate to the nearest valid NCO value,
and will auto-calculate the correct register values in the field next to it.
• Click Configure CDC
