Note 22. In DSD mode, the signal level is ranging from 25% to 75%. Peak levels of DSD signal above this duty
are not recommended by SACD format book (Scarlet Book).
Note 23. The output level is assumed as 0dB when applying a 1kHz sine wave in 25~ 75% duty.
*Digital filter characteristics are based on simulation results.
