Production Data

WM8523

PD, Rev 4.1, August 2011

In DSP mode, the left channel MSB is available on either the 1st (mode B) or 2nd (mode A) rising edge of

BCLK (selectable by AIF_LRCLK_INV) following a rising edge of LRCLK.

Right channel data

immediately follows left channel data. Depending on word length, BCLK frequency and sample rate,

there may be unused BCLK cycles between the LSB of the right channel data and the next sample.

In device master mode, the LRCLK output will resemble the frame pulse shown in Figure 19 and Figure

20. In device slave mode, Figure 21 and Figure 22, it is possible to use any length of frame pulse less

than 1/fs, providing the falling edge of the frame pulse occurs greater than one BCLK period before the

rising edge of the next frame pulse.
