[sdiy] SSM2164 dual sine VCLFO PCB available

[Neil Johnson]

Hi all,

Hope this is not too commercial...

I've just finished characterizing my latest module - a dual sine VCLFO based on an SSM2164.  One VCLFO produces three sinewave outputs, 120 degrees apart, over a range of around 100Hz down to 12 minutes, and a second auxiliary VCLFO with a diode-shaped single sine output from 300Hz down to around 7 minutes.

By changing the capacitors this could also comfortably work in the audio range, but there is no temp.compensation so I wouldn't recommend it for stable VCO usage.  Alternatively, a couple of component changes and this will go down to an hour or more per cycle.

Details here:

Boards available if anyone wants to build one too.

Cheers,
Neil
