I wanted to build a circuit which would produce a set of signals of different frequencies in different channels simultaneously using a single reference source. I also want the frequencies to be changeable. I am looking to generate frequencies in kHz and MHz range. On searching on the web I came across PLL. I wanted to know if I can do it using PLL or any other methods. It should be fully analog.
 

Hi,

Yes, I'd use a PLL.

Depending onthe frequency relationship, jitter requirements and so on you also may use NCOs, or integer dividers in a PLD.

Other parameters to decide....before asking for a chip...
* signal waveform (timing, duty cycle range, precision rise and fall time...)
* signal voltage amplitude
* signal current drive capability
* frequency resolution and range
...

Hi,

maybe something like: CDCE949

I think that DDS would be much better idea than a PLL - no need to use VCO for different frequency bands.
