Digital Output Modes
The digital output modes (SDOUT1, SDOUT2, SDOUT0) are described in Sections 2.2.1 through 2.2.3.
2.2.1
MSB-First, Right-Justified, Serial-Interface Format
The normal output mode for the MSB-first, right-justified, serial-interface format is for 16, 18, 20, or 24 bits. Figure 21
shows the following characteristics of this protocol:
Left channel is transmitted when LRCLK is high.
The SDIN(s) (recorded) data is justified to the trailing edge of the LRCLK.
The SDOUT(s) MSB (playback) data is transmitted at the same time as LRCLK edge and captured at the
next rising edge of SCLK.
If the LRCLK phase changes by more than 10 cycles of MCLK, the codec automatically resets.
