Input Load Capacitor for The CY22392

Question: An input load capacitor must be set when using crystal resonator. Does the value correspond to c1*c2/(c1+c2)?

 

Answer:

Yes, the capacitor load value is calculated by c1*c2/(c1+c2). If the capacitor is programmed to be 12 pf then a 24 pf capacitor will be on each leg of the crystal.
