Wow, 150PPM typical/100PPM guranteed is pretty big pull range for VCXO. Wonder if they use a special cut to get that much. One trick I've seen is to parallel crystals to increase pull range.
I have used PS2 from 74HCT9046 up to 1.0-2.5 MHz with no problems so you will have no difficulty at the word rate.
