Notes: 6 . The passband and stopband frequencies scale with fs. PB=0.4535fs, SB=0.5465fs
7 . The analog modulator samples the input at 6.144MHz for an output word rate of 48kHz.
There is no rejection of input signals which are multiples of the sampling frequency
(that is: there is no rejection for n x 6.144MHz±21.768kHz, where n=1,2,3…).
8 . The calculating delay time which occurred by digital filtering. This time is from the input of analog signal to
setting the 24bit data of both channels to the output register. 40.7/fs at HPF:ON.
