Note 10. 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 11. The calculating delay time which occurred by digital filtering. The time is from the input of analog signal to
setting the 16bit data of both channels to the output register for ADC.
For DAC, this time is from setting the 16bit data of both channels on input register to the output of analog signal.
