Cd4046 Application Circuit. This power reduction has particular significance for portable battery operated equipment. The pll described in this application report is the cd4046b which consumes only 600 µw of power at 10 khz a reduction in power consumption of 160 times when compared to the 100 mw required by similar monolithic bipolar plls.

Cmos micropower phase locked loop cd4046 datasheet cd4046 circuit cd4046 data sheet. Today i ll discuss the detailed introduction to cd4046 which is a micropower phase locked loop pll that comes with a common comparator input and a common signal input amplifier between a low power linear voltage controlled oscillator vco and two different phase comparators the phase locked loop as the name suggests is a loop where the phase of the output signal is compared with the phase of the input signal using a phase detector between two signals. The value of this resistor is used in conjunction with the value of the timing capacitor c connected between pins 6 and 7 to set the operating frequency range of the vco when it is controlled by a voltage applied to pin 9.
The hc hct4046a pll with vco is a high speed cmos ic designed for use in general purpose pll applications including frequency modulation demodulation discrimination synthesis and multiplication.
This power reduction has particular significance for portable battery operated equipment. In a normal cd4046 application a resistor referred to as r1 is connected from pin 11 to ground. The pll described in this application report is the cd4046b which consumes only 600 µw of power at 10 khz a reduction in power consumption of 160 times when compared to the 100 mw required by similar monolithic bipolar plls.
