Serial Audio Interface Formats
The CODEC_SP and SAI_SP digital audio serial ports support five formats with varying bit depths from
16 to 24 as shown in
isters,
For the diagrams below, Single-Speed Mode is equivalent to Fs = 32, 44.1, 48 kHz; Double-Speed Mode
is for Fs = 64, 88.2, 96 kHz; and Quad-Speed Mode is for Fs = 176.4, 196 kHz.
