Is the CLKMODESELECT pin on AD9951 3.3V compatible or only 1.8V compatible? Applying 3.3V on this pin seems to cause latchup of the whole device.
Thank you for your final response, which forces me to have 2 additional questions:
Will this be added to the datasheet or will the datasheet stay incomplete?
Will AD refund devices damaged by the non-complete datasheet (or at least apologize)?
To answer your previous question, AVDD and DVDD were both 1.8 V, DVDD_IO was 3.3 V.
