QN9083DUK External High Frequency Oscillator pin Vin min value

[neil_dewey]

Does anyone know the Vin min operating voltage for the 32MHz / 16MHz External High Frequency Oscillator pin? Pin in question is XTAL_IN (pin 1C on the WLCSP package). Plan to use an external 32MHz Square Wave Oscillator with an nominal clock output voltage of 1.8V The QN9083DUK will be powered from a 1.8V source. The documentation specifies that the External High Frequency input has a Vin min of 0V, which obviously not practical. Many thanks

Hello,

It will depend on your oscillator, nonetheless, if your oscillator goes from 0 to 1.8V it should not have problems, please take into consideration that you oscillator will need to meet the requirements of the digital 0 level and the 1 level of the chip.
