Pre-Production
w
In DSP mode, the left channel MSB is available on either the 1
BCLK (selectable by AIF_LRCLK_INV) following a rising edge of LRCLK.
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.
