AD9957 XTAL_SEL

What voltage levels should the XTAL_SEL pin be connected to?  I almost assumed it was a 3.3v CMOS input as those are the only logic specs shown in the datasheet, but according to the evaluation board schematic it should be connected to either AVDD (+1.8V) or AGND.  However, I also see the schematic has mislabeled pin 83 as AGND when it should be AVDD, so I don't know if this could be just another typo.
