Hi, m trying to implement PLL for FSK demodulation. NE565 is very simple in use and has very simple formulae bt the problem is that m nt going on hardware. i just need to simulate first. i tried Proteus bt proteus unfortunately doesnt has a model for NE565.... see 'pic1' ...... so i need an NE565 model or whatever is required to make it run ..... i've Proteus 7.1sp2
as NE565 didnt run so i tried 4046 .... it has the model bt the prob is that the formulae to set 4046's VCO's free running freq and capture range and lock range arent that simple...... see 'pic2' .... plz guide me with this .... abt the all 3 terms fo, fc and fL plz
