10.1.6 PLL clock output
• The PLL clock output is controlled by the PLLACC, PLLDV1, PLLDV2, or PRSEL[1:0].
• PLLACC can be used to generate a PLL lock frequency for each S/PDIF input sampling frequency band.
Table 10.2: PLL Clock Output Frequencies (Bold settings are recommended values.)
• If 128kHz, 176.4kHz or 192kHz input is received when the PLLACC is set to 0 and the PRSEL [1:0] to 01, the DC
characteristics of output directly sent to the RMCK pin cannot be guaranteed. In such a case, set the frequency to one
half or quarter of the PLL clock frequency (PRSEL [1:0]=00 or 10).

PLL fixation output
*: When the data is judged to exceed the value of
PLLACC=1 (Fixed multiple outputs for each input fs band)
FSLIM [1:0] which limits the reception frequency of
the input S/PDIF, processing similar to PLL
unlocking is carried out and the processing does not
proceed to the subsequent step. The clock source is
automatically switched to the XIN source.
