AD9656 max. SPI supply voltage

The Absolute max. voltage for SVDD is given with 2.0V (datasheet page 11).
However the evaluation board uses 2.5V. Why is that? All SPI signals are
tolerant to 3.9V. Is it possible that SVDD can be 3.9V too? Otherwise, what's the purpose of SVDD pin?

If the SPI really just work on 1.8V level, what's the recommended voltage level translator to 3.3V CMOS?
