Frequency Multiplier Using Pll 4046. The frequency multiplication ratio is pin selectable over a wide range of values from 4 through 40 to accommodate a broad spectrum of user needs. The 4046 74hc4046 series phase locked loop ics are extremely useful parts that can be used in a lot of applications like frequency synthesis multiplication signal synchronisation data extraction etc.
No external filter components are needed. The circuit is based on a 4046 type micropower phase locked loop ic and uses a divide by 12 counter inserted in the loop to force the pll s vco to run at 12 times the input frequency. A square wave input of 1khz is also provided which is to be applied at the input and output to be observed on cro.

Unfortunately many first users have run into difficulties due to misleading and very old never revised data sheets and erroneous application notes. Adtron s phase lock loop pll as frequency multiplier and synthesizer is a versatile self contained stand alone unit useful in the study and demonstration of the application of pll as frequency multiplier. The 4046 phase locked loop pll chip is a fantastic chip to experiment around with. The frequency multiplication ratio is pin selectable over a wide range of values from 4 through 40 to accommodate a broad spectrum of user needs.
