      I read the adau1979 datasheet with some confusion, as follows:


    As above, tABH: min 10ns

                     tABL: min 10ns

                     tABDD: max 18ns

   In I2S mode, the i2s data delayed by 1 BCLK, that

                     tABDD = tABH + tABL = min 20ns

        but tABDD need less than 18ns,Did I understand something wrong? pls help to understand this question, thanks.
