    HI,
    Ok i got that in the datasheet itself. But what is that frequency clock, voltage clock?
    How can i vary the output frequency?
    I dont need the manual control of frequency. It seems the 47k pot is used to vary the frequency. is it correct?
    In my circuit, iam having a working voltage which decides the frequency output.
    using that voltage i need to control the output frequency of this IC.
