I believe that note 6 on page 4 of the UCD9240 datasheet is an error. It says "The PMBus command: EADC_SAMPLE_TRIGGER defines the start of the 32ns ADC sample window. So the minimum EAD_SAMPLE_TRIGGER time is 208 + 32 = 240 ns." My understanding is that the 32 ns sample window immediately precedes (in time) the trigger point, and that the actual minimum EAD_SAMPLE_TRIGGER time is 224 ns.
