Serial Audio Interface Formats
The DAC_SP and ADC_SP digital audio serial ports support five formats with varying bit depths from 16
to 24 as shown in
“Functional Mode (address 03h)” on page 43
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.
