Note 46. This value is the time from the rising edge of LRCK, SYNCA or SYNCB after data is input to rising edge of
LRCK after data is output, when LRCK, SYNCA or SYNCB for Output data corresponds with SYNCA or
SYNCB for Input.
fs: LRCK Frequency, fs2: SYNCA Frequency, fs3: SYNCB Frequency.
Note 47. This value includes group delay of DAC digital filter.
