Table 10 Derivation of Sample Rates in Normal / USB Modes
Note that, in USB mode, the ADC / DAC sample rates do not match exactly with the commonly used
sample rates (eg. 44.118 kHz instead of 44.100 kHz). At most, the difference is less than 0.5%,
which is within normal accepted tolerances. Data recorded at 44.100 kHz sample rate and replayed
at 44.118 kHz will experience a slight (sub 0.5%) pitch shift as a result of this difference.
Note: USB mode cannot be used to generate a 48kHz samples rate from a 12MHz MCLK; the FLL
should be used in this case.
The user must ensure correct synchronisation of data across the digital interfaces. This is particularly
important when different sample rates are used, as described above.
