Cd4046. The two phase comparators have a common signal input and a common comparator input. In fact it s so versatile that we ll spend the next three sessions exploring it.
Cmos micropower phase locked loop cd4046 datasheet cd4046 circuit cd4046 data sheet. I get that cd4046 is used to lock at resonant frequency of coil but i dont understand how voltage controlled oscillator is used to modulate audio to output. The 4046 phase locked loop pll chip is a fantastic chip to experiment around with.
The ic 4046 is a phase locked loop ic of cmos digital combined analog and digital chip.
I get that cd4046 is used to lock at resonant frequency of coil but i dont understand how voltage controlled oscillator is used to modulate audio to output. The vco signal and an input signal are sent to a phase comparator which generates an error voltage part to any difference in frequency between two signals. A versatile building block for micropower digital and analog applications phase comparator i is an exclusive or network that operates analogously to an overdriven balanced mixer. Scha002a 6 cd4046b phase locked loop.
