Serial Audio Interface Formats

The DAC_SP and ADC_SP digital audio serial ports support 5 formats with varying bit depths from 16 to

24 as shown in Figure 7, Figure 8, Figure 9, Figure 10 and Figure 11. These formats are selected using the

configuration bits in the registers, “Functional Mode (address 03h)” on page 33 and “Interface Formats

(address 04h)” on page 34. For the diagrams below, single-speed mode is equivalent to Fs = 32, 44.1,

48kHz; double-speed mode is for Fs = 64, 88.2, 96 kHz; and quad-speed mode is for Fs = 176.4, 196 kHz.
