Hi, I am connecting and coding for FDC2112 ,while setting i don`t know what is the value of Fref ?
And what is the value of Int.Osc ?
Please help me, Thanks !

Hello,
The int Oscillator can be set up to 55Mhz and the setting depends on the settings chosen as per your application.
Section 9.3.1 of the datasheet clearly describes the clock architecture and the operation.
here is the image of the Clock architecture tree
Here is the recommended settings based on your operation that needs to be selected.
Hi Arjun,
Thanks for your answer
I thought that it was necessary to set the value for Fref but i have not found a way to set this value, while if it is Fclkin, depending on the frequency of the external pulse, other parameters can be calculated based on this reference frequency.
as you write: "The int Oscillator can be set up to 55Mhz and the setting depends on the settings chosen as per your application."
-> How do i set the value for internal oscillator?
Best Regards !
