Note 14. The passband and stopband frequencies scale with fs. For example, PB = 0.4535×fs (@±0.01dB), SB =
0.546×fs.
Note 15. The calculating delay time which occurred by digital filtering. This time is from setting the 16/20/24bit data of
both channels to input register to the output of analog signal.
