I combined CD4046 and CD4522 to make a frequency doubling circuit, but it cannot achieve frequency doubling. Can you help me see the circuit diagram and the simulation diagram?

What is the frequency of the signal given by pin 14 of CD4046 of U2? The frequency of the input signal does not seem to be high. Please check the manual.

It is nothing more than circuit connection error, insufficient power supply voltage, incorrect parameter setting, undetected interference, etc.
