Note 23. Frequencies (20, 100, 200kHz) will be doubled and quadrupled in 128fs mode (DSDSEL[1:0] bits =
“01”) and 256fs mode (DSDSEL[1:0] bits = “10”), respectively.
Note 24. 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 25. It is assumed that the output level is 0dB when the input signal is 1kHz and the duty range is between
25 ~ 75%.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.
