DSP MODE A
In DSP Mode A, the MSB of Channel 1 left data is sampled on the second rising edge of BCLK
following a LRCLK rising edge. Channel 1 right data then follows. For the PAIF Receiver, Channels 2
, 3 and 4 follow as shown in Figure 17.

For the SAIF receiver, only stereo information is processed.
Figure 18 DSP Mode A Timing Diagram – SAIF Receiver Input Data
The MSB of the left channel of the output data changes on the first falling edge of BCLK following a
low to high LRCLK transition and may be sampled on the rising edge of BCLK. The right channel data
is contiguous with the left channel data.
