[ARC5] Programmable Oscillators

[Ian Wilson]

Note that you can get a complete PCB with the AD8950 plus 125MHz
xtal oscillator, lowpass filter, LED, etc, for $4.49 with free shipping from
HK on eBay. Handy building block if DDS is OK for you.

I purchased two of these, now reduced to one when I forgot that they are
3.3v supply units (AD8950 now has a smoke-release-friendly hole in
the packaging). It may even have glowed for a moment <g>.
