Apparently my last post didn't get posted even though it waited for over 24 hours to be posted, so I'll just rephrase what I've said there.
Diver300:
I'm aware it can be done in fewer ICs and that it is an old technology.
I'm really new in the world of electronics and only have limited experience in the simulator. This was supposed to be the first thing I'd really make. It is by no means permanent it is just a learning project and the parts in it are based on what I could easily obtain in a reasonable time line.
Since I posted the answer which didn't pass through, I did look around a bit and I could get some CMOS ICs. I've revised the scheme to use 4511, 4518... and to use two 4040s for the frequency divider. I could also use 4060 and 4013 to get the same result but the simulator doesn't seem to like 4060.
As for the "voltage drop" I've tried to simulate Colpitts oscillator posted by MikeMl in a completely different thread (no links this time - hopefully this post will pass). It did produce the right frequency (and was the only oscillator I managed to get to do that in the simulator) but the output was only 1.88V.
I'm looking into some other oscillators and it appears you're right - the simulator doesn't like crystals. I guess I'll just have to try it out to see...
I also checked the Pierce oscillator, I might as well use that.
MikeMl:
Thanks. I probably won't use CDP1802, but the schematic does help
MrDEB:
I most likely wouldn't be able to do that, both because of the lack of experience and knowledge and because of the unavailability of the parts around here. I'd have to wait quite a bit for them to get here...
That might be a project for the future, though.
