Hi,
I can't find any information in the datasheet regarding the voltage level range for this pin? The only thing I can find is this text in paragraph 9.2.1:
"When using an external clock source such as an oscillator, the reference clock should have a ±100 PPM or better frequency stability and have less than 50-ps absolute peak-to-peak jitter. XI should be tied to the 1.8-V clock source and XO should be left floating."
Anyone here that know the minimum and maximum voltage levels for this pin? Can this pin be driven with a 3.3V oscillator? Also, is the pin protected with diodes?
Thanks.
