8.3.4 Digital Down Converter
The ADC364x includes an optional on-chip digital down conversion (DDC) decimation filter that can be enabled
via SPI register setting. It supports complex decimation by 2, 4, 8, 16 and 32 using a digital mixer and a 32-bit
numerically controlled oscillator (NCO) as shown in Figure 8-18. Furthermore it supports a mode with real
decimation where the complex mixer is bypassed (NCO should be set to 0 for lowest power consumption) and
the digital filter acts as a low pass filter.
Internally the decimation filter calculations are performed with a 20-bit resolution in order to avoid any SNR
degradation due to quantization noise. The Section 8.3.5.4 truncates to the selected resolution prior to outputting
the data on the digital interface.

8.3.4.1 DDC MUX
The ADC364x family contains a MUX in front of the digital decimation filter which allows the ADC channel A
input to be connected to the DDC of channel B and vice versa.
