Stable CEM3340/AS3340-based VCO
CEMosc is a stable AS3340 based VCO which tracks beautifully, and is feature rich. Easy to build and calibrate too.
CEMosc has at it’s heart a CEM3340 or AS3340. You can source your own chip, of buy AS3340 direct from me when you order your PCB set and panel.
CEMosc features:
Onboard voltage regulation for tuning and tracking stability
A rotary octave switch as well as a fine tune knob
Both manual PW as well as PWM are available
Linear and Exponential FM inputs, each with attenuators
Both soft and hard sync
Sawtooth, Triangle and Pulse outputs
These merchants probably sell this module. Huh?
