Digital Interface Format
The device will accept audio samples in either I²S or Left-Justified digital interface formats, as illustrated in
Table
The desired format is selected via the I²S/LJ pin. For an illustration of the required relationship between the
LRCK, SCLK and SDIN, see
SCLK must have at least 32 cycles per LRCK period in the Left-Justified format.
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 http://www.cirrus.com.
Internal High-Pass Filter
The device includes an internal digital high-pass filter. This filter prevents a constant digital offset from cre-
ating a DC voltage on the analog output pins. The filter’s corner frequency is well below the audio band; see
the
Combined Interpolation & On-Chip Analog Filter Response
