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 Figures 11 to 15. These formats are selected using the configuration bits in the registers,

“Functional Mode (address 03h)” on page 43 and “Interface Formats (address 04h)” on page 45. 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.
