Digital Interface Format
The device will accept audio samples in 1 of 4 digital interface formats, as illustrated in Table 5.
The desired format is selected via the DIF1 and DIF0 pins. For an illustration of the required relationship
between the LRCK, SCLK and SDIN, see Figures 3-5. For all formats, SDIN is valid on the rising edge of
SCLK. Also, SCLK must have at least 32 cycles per LRCK period in format 2 and 48 cycles per LRCK period
in format 3.
For more information about serial audio formats, refer to Cirrus Logic Application Note AN282: The 2-Chan-
nel Serial Audio Interface: A Tutorial, available at www.cirrus.com.
