Aries-based CEM3340 VCO
This is very much based on the Aries AR-338 PMS VCO, which features phase modulated sync and a pan-pulse output. The AR-338 used a SSM2030, so it was not too hard to modify the sub-sections to suit the CEM3340. As you can see, for such a feature rich VCO, there are not all that many components.

These merchants probably sell this module. Huh?
