[sdiy] DCO

[Jerry Gray-Eskue]

Tom<<There are various reasons; DCOs generate genuine analogue ramps,
which is important to some people; Related is the fact that DCOs can
easily generate sync waveforms without aliasing, which is *hard* to
do with digital oscillators; DCOs have a relatively low processor
overhead, since you only have to deal with a timing reset pulse once
per wavecycle instead of dealing with generating a new sample at x
KHz. That leaves you time to do modulation processing on the same chip.>>

This sounds a lot like a design I have been finishing up.

I had not seen anything similar to my design and am now wondering if I have
reinvented the wheel.
What exactly is a DCO? Are there any schematics / info available on them?
What have they been used in?
