Note 6 .The passband and stopband frequencies scale with fs (system sampling rate).
For example, ADC is PB=0.431*fs(@-0.55dB), DAC is PB=0.454*fs(@-0.1dB).
7 .The calculating delay time which occurred by digital filtering. This time is from the input of analog signal to
setting the 16 bit data of both channels to the output register for ADC.
For DAC, this time is from setting the 16 bit data of both channels on input register to the output of analog
signal.
