i need an ic that i can control its frequency using volt
and it generates sin wave ???
can any body help?
 

You can make an oscillator with a varactor. Varactor is a diode that works like a voltage-controlled capacitor that changes the natural frequency of the oscillator. If you can live with a square wave output, you can find a voltage to frequency converter (VFC) chips. Just look them up on Google.

Click to expand...

Which frequency range?
 

It is VCO. Please specify your frequency range and voltage range
 

the frequency from 88mhz till 108mhz
 

Search any VCO from IDT, pericom, TI, Cypress... you can get an answer, Most of the time, they are called VCXO with temperature compensated VCO
 

Hey mr_byte31
I also want the same VCO of frequency range 88MHz to 108 MHz
Did you find any useful IC
If yes please forward it to me
