I want to lock 10kHz VCO output with 50Hz sine wave by using CD4046b with 74LS390 (divider). what are the values of vco components and filter components with 12v Vdd supply to 4046IC

 

Hello,

Have a look at the following thread:

In Post #8 I posted some formulas for calculating the component values.

Sir actually I have used this formula but it didn't work
really want the values of components

 

This sounds a lot like homework. Just guessing.

 

Not designing synchronized pulses for inverter

While you have an support or you know then share it

 

Hello,

I just posted the link to the formula, but here is the complete thread:

The N in your circuit should be 10.000 / 50 = 200.
This can not be managed with a single 390 chip.
