4 Quick Start Procedure for Complex Decimation Mode

The ADC32RF5x device family provides up to two digital down converters (DDC) per ADC channel supporting a wide range of instantaneous bandwidth IBW coverage - from single wide band mode with 8x complex decimation to up to two narrow band channels with as high as 128x complex decimation.

When operating in complex decimation mode, the appropriate NCO is used as an intermediate frequency to the complex mixer. Similar to the bypass operating mode, the user has the option to enable averaging of each internal pair of ADCs. This section will provide two example configurations for operating the ADC32RF5xEVM in 8x and 128x decimation modes.
