Precision of NVCC_PLL

Hi all.

I want to use a 24M oscillator(3.3V) to connect to XTALO. But the logic level of this forcing clock must not exceed the NVCC_PLL level(Typical Programming Operating Range is 1.0V to 1.2 V with the nominal default setting as 1.1 V). 

My question is whether i can use two resistances to divide the output of oscillator to satisfy the requirement of XTALO DC parameters.And the precision of NVCC_PLL.

Hi,

 

This has not been tested but it looks like it could work. Please just take into considerations that 'the crystal must be rated for a maximum drive level of 250 uW as it is stated in datasheet.

 

Best regards,

Felipe
