Re: RE: [sdiy] Black Magic oscillator cans

How about little DDS?
They make small low-power 10-pin devices now.
With that you have both tunability (DC to several MHz)
and 32-bit precision (dependent on external clock source
of any frequency easy for you to generate).
Of course you need a micro to take care about tuning,
but it can be done so quick nobody would notice it's not
analog.
