Re: DCO/VCO Fine clock output?

Hello Chris,


... If lower performance is OK,
or lower power consumption and lower cost interests you then some kind of
VCO like the one out of a 4046 IC might do what you want.


That one has quite poor linearity. The LM331 is much better. AD also offers a few V/F converter chips that are top notch but cost a bit more than the LM331.

It is also possible to linearize the 4046 via a feedback loop but then the cost approaches that of the LM331.
