Notes: 14. The passband and stopband frequencies scale with fs.
For example, 20.02kHz at –0.02dB is 0.454 x fs. The reference frequency of these responses is 1kHz.
15. The calculating delay time which occurred by digital filtering. This time is from setting the input of analog
signal to setting the 24bit data of both channels to the output register for ADC.
For DAC, this time is from setting the 20/24bit data of both channels on input register to the output of analog
signal.
16. fs=96kHz.
