The Oversampling Factor (O_FAC) is related to OCLK and SCKT by the following expression:

1) OCLK_freq = O_FAC * LRCKT_ Freq

(DAC relation)

2) OCLK_ Freq = 2 * (1+PCM_DIV) * 32*

LRCKT_Freq (when 16 bit PCM mode is used)

3) OCLK_ Freq = 2 * (1+PCM_DIV) * 64*

LRCKT_Freq (when 32 bit PCM mode is used)

4) PCM_DIV = (O_FAC/64) - 1 in 16 bit mode

5) PCM_DIV = (O_FAC/128) - 1 in 32 bit mode

Example for setting:
