HMC832 SPI Voltages

SPI pins are logic CMOS inputs. Datasheets tells that the maximum voltage at logic inputs should not exceed 60 % of DVDD. If i use 3.3 V DVDD, would the device work properly with 3.3 V applied at SPI pins. Most of teh microcontrollers SPI interface work at 3.3 V, so I would like to operate the PLL SPI interface at 3.3 V. But datasheet says that it should not exceed 60% of 3.3 V (if 3.3V DVDD is used).
