Digital Gyros power

As I noticed in Digital gyros, The PDD, is the LDO power supply which produce the AVDD and DVDD voltages.

Does the PDD, in ADXRS453, is the reference of the voltage level in SPI ? and it should be connected to 3.3v for microcontroller?

The problem is I have no data about sensor performance in 3.3v PDD, because the performance table in datasheet is just for 5v.
