Hello, hoping you are all having a great day I need help with this circuit.



This is the Phase-Locked Loop Using Internal Phase Detector circuit extracted from the datasheet of the MAX038, my question is, What are the formulas of the frequency and/or duty cycle of the output signal? The idea is to get a squarewave signal of 20MHz and a duty cycle of 50% if posible.

Thank you in advance.

 

Usually the description of the method of determination is given in the product data sheet. Maxim has been rather good about that in the distant past, as I recall. So visit the MAXIM website for the data sheet and application notes.
I would AVOID the you-tube cartoon channel in the search. TOO much garbage among the selections.
