SWITCHING CHARACTERISTICS - SERIAL AUDIO INTERFACE
11. Not all sample rates are supported for all clock ratios. See table “Common Clock Frequencies” on
page 12 for supported ratios and frequencies.
12. In Internal SCLK Mode, the duty cycle must be 50%
±1/2 MCLK period.
13. The SCLK / LRCK ratio may be either 32, 48, 64, or 72. This ratio depends on data format and
MCLK/LRCK ratio. (See Figures 7-10)
