Are there any ICs that multiply the frequency of a sinusoidal signal? I have 60Hz signal coming in, and I'd like to make it say...a 20khz signal. Is there an IC that can do this?
Right now I'm just rectifying the 60Hz signal, then using it to drive an oscillator (555 timer in astable mode really). It works fine, but it seems like I shouldn't have to do all this.
I know that modulation ICs exist, but then, I'd have to set up a sinusoid of a different frequency, and I've opened up a new can of worms, I think.
Suggestions are welcome
thanks
