Note 12. The passband and stopband frequencies scale with fs.
For example, ADC: PB=0.454 x fs(@-1.0dB), DAC: PB=0.454 x fs(@-0.1dB).
Note 13. The calculated delay time caused by digital filtering. This time is from the input of an analog signal to setting the
20bit data of both channels to the output register of the ADC and includes the group delay of the HPF.
For DAC, this time is from setting the 20bit data of both channels on input register to the output of analog signal.
