Note 13. The passband and stopband frequencies scale with fs (system sampling rate).
For example, PB=0.4535×fs (@±0.05dB), SB=0.546×fs.
Note 14. Calculated delay time caused by the digital filter. This time is measured from setting the 16/24bit data
of both channels to input register to the output of the analog signal.

Note 15. The SMUTE pin and DIF pin are not included. The SMUTE pin has an internal pull-down resistor (typ.100kΩ)
and the DIF pin has an internal pull-up resistor (typ. 100kΩ).
