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?
Solved! Go to Solution.

Hi,
The oscillator should work at 1.8V as per my understanding since its XTALIN is considered as an input pin. Please ensure the following parameters are met:
24 MHz ± 100 ppm, Parallel Resonant, 500 uW drive level
