The PRF Frequency (TPWMP) of the Sub-woofer channel is half of the frequency defined in Table 45

in order to reduce power dissipation in the output stage.

Table 45 Output Bitclock Frequency

Notes:

The correct Output Bitclock Frequency (TOBCLK) is generated by the built-in PLL of the WM8608

device. The incoming clock must meet the jitter specification defined in Table 3.

OUTPUT PHASE

The Phase control word determines whether the output of each channel is non-inverted or inverted.
