AD7770  Delay from SYNC_IN to first DRDY

I'd like to know how to estimate the delay from SYNC_IN pulse to first DRDY. I guess it depends on ODR and mode. But the conditions of tINIT_SYNC_IN are only 16 kSPS, high resolution mode. And I'd like to know from what timing the delay have to be estimated in an accurate way,in other words, when the filter restart. From first MCLK Rise After SYNC_IN Rise?
