Cd4046 Circuits. In this session of logic noise we ll be playing around with the voltage controlled oscillator from a 4046 phase locked loop chip and using it to make musical pitches. This is a rather simplistic explanation of a 74hc4046 phase locked loop with a vco because whole books have been devoted to phase locked loops offering varying degrees of mathematical complexity.
Cmos micropower phase locked loop cd4046 datasheet cd4046 circuit cd4046 data sheet. The 4046 chip is a phase locked loop. The pll structure consists of a low power linear vco and two different phase comparators having a common signal input amplifier and a common comparator input.
The pll structure consists of a low power linear vco and two different phase comparators having a common signal input amplifier and a common comparator input.
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. 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. The pll structure consists of a low power linear vco and two different phase comparators having a common signal input amplifier and a common comparator input.
