1.5.4 Clock and Data Flow for DAI Input with Matched DAO Fs
Figure 1-11. DAI Clocking with Fixed Output Fs
The DAI clocking architecture is used when any serial audio data source is connected to the DAI header.
illustrates this clocking configuration. Note that the incoming DAI data is synchronized to the
DAO using a common MCLK.
This is a more traditional clocking architecture for serial audio data, where the DAI Fs and the DAO Fs are
synchronous. In this configuration, the SRC is bypassed for the DAO.
