    Cy7C68053 XTALIN clock input voltage level


      Hi all

           I use Cy7C68053 for its 1.8V IO voltage. And I use a oscillator as the clock source connecting to the XTALIN pin, and the XTALOUT pin is left float.

      VCC_IO is 1.8V and the AVCC is 3.3V .

      My question is at which voltage level should the oscillator work at, 1.8V or 3.3V?
