Power On condition for ADN4670


I need to have all the outputs enabled with ADN4670 on Power-On and later through programming, I want to disable some of the outputs.

In the programming section of datasheet it is mentioned that this is possible, provided the inputs EN and SI are left open circuited.

But this wont be the the case, since those lines will be connected to a processor. If the processor pins are tristated on Power On, will this work correctly?

Also is there any similar device for CMOS clock distribution (1:6 outputs) and enable for each output?
