7.3.4 Digital Down Converter
The ADC3683-SP includes an optional on-chip digital down conversion (DDC) decimation filter that can be
enabled via SPI register settings. Supporting 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 7-17.
Supporting a mode with real decimation where the complex mixer is bypassed (NCO is 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 to avoid any SNR degradation
due to quantization noise limitation. The Output Formatter truncates to the selected resolution prior to outputting
the data on the digital interface.

7.3.4.1 DDC MUX
The ADC3683-SP contains a MUX in front of the digital decimation filter which allows ADC ChA to be connected
to DDC ChB. This feature is enabled and controlled using the SPI interface. Subsequently the output interface
corresponds to the DDC channel A and B.
