Do we need to provide same voltage for microcontroller I/O and oscillator?

I can use 1.8V that is available in my board.This doubt came to my mind what will happen if the I/O voltage is different from oscillator voltage

hi h,

If the stated PIC Input limits are confirmed as you posted, why are you querying the use of 3.3v on the osc module?
Have you tried the Osc to PIC connection at these voltages?
