Note 8 :
These frequencies scale with the sampling frequency(fs).
Note 9 :
Stopband is 26.5kHz to 3.0455MHz at fs=48kHz.
Note 10 : Passband is DC to 21.5kHz at fs=48kHz.
Note 11 : The analog modulator samples the input at 3.072MHz for a system sampling rate of
fs=48kHz. These is no rejection of input signals at those bandwidths which are multiples of
the sampling frequency (n x 3.072MHz
±
22kHz ;n=0,1,2,3…).
Note 12 : The calculation delay time occurred by digital filtering. This is the time from the input of
analog signal to setting the 20bit data of both channels to the output registers. GD=29.3/fs.
