Function of VCXO pin in CY24204

Question: In the CY24204 what is the function of the VCXO pin and how should it be connected if we do not use it?



The VCXO pin allows you to pull the output frequency away from the nominal frequency by several ppm. If you do not need this feature, then you should use a resistor divider network to hold VCXO at VDD/2. The exact resistor values are not important, but an example value would be 470 ohms. Please note that the VCXO should never be left floating.
