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?

 

Answer:

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.
