AD5933 - Logic high voltage vs VDD - is there a maximum?

I propose to use 3V VDD but supply the logic inputs under 3V3.  The 5933 Specifications (Table 1) sets a _minimum_ value for the logic high voltage as 0.7xVDD but doesn't list an upper value for logic high voltage. Can logic high voltage exceed VDD, and if so, by how much ?
