resetting a filter

Hardly. One of my nicer achievements this year involved designing a chip to measure magnetic fields in the gap of a heavy truck clutch, controlling the closure rate to minimize "jerk"... though I see no hope for you (Larkin ;-) ...Jim Thompson

See. Told you that you didn't understand. You are really stupid. ...Jim Thompson

If you think I'm gutless try me.

As for you, you remain a village idiot... your reading comprehension really sucks.

How did you manage to get your degree? Ah! I see! Tulane is a diploma mill. ...Jim Thompson

What does "ECL based 555 type" mean?

Just take an MC12061, replace XTAL with a C, add resistors from each crystal node to ground... voila, a very fast 555... even with a TTL output.

There was a PECL version on my MC4024 voltage-controlled multivibrator, but I can't locate it now... maybe no longer made. The MC4024 is actually PECL internally, with a translator to TTL. It'll do ~30MHz, voltage-controlled about 3.5:1 (or more) tuning range. ...Jim Thompson

"Fastest possible", assuming built from production parts, would cost something in the $2K range. I'd guess it could astable at a GHz or so.

You sound like a guy we have employed. We call him the screw driver or golden child, because he has blond hair. If you were to listen to him you'd swear there isn't anything on this planet he does not know about and he has done things in his life time that would take most of us a spanned of 200 or more years to achieve..

He even goes out of his way to make comments about successful people we deal with are wrong in their assessments of many things we pay good money for.

Yup, he's a walking wonder and everything that he has actually done has been nothing but thumbs and fingers and mostly failures but yet he still has the nerve to say that others that are successful in their fields make gross mistakes, something that he claims he can pick up on and do better of course.

Does that remind you of any one you know? It should.

This kind of brings a smile to my space actually, because today I called him out on the carpet on several things that has been spewing out of his mouth. He was very quiet for the rest of the day. Of course, I did this in front of every one else to see. I know it's only temporary, for he'll go home and sit on google, like you do, and stuff some more unreliable information in his head that he only understands a small percentage of to pollute the work front tomorrow..

You first.

Then they would not be "perfectly respectable".

You are the one who claimed that there would be a 100MHz oscillation.

Explain it.

But he didn't say what you claimed he said, and that decidedly makes YOU the gutless, slimy asshole for claiming that he said it.

You are, in fact, the slimyest asshole in the group.

If you could keep you mouth off people, AND off what you think their capacity for electronics is, you *might* recover.

Brazed and welded-in hard wired self importance is hard to extricate, however.

You must try, or you are worse than anything you ever said or thought about anyone else anywhere.

Did you miss it ?:-) Shee-e-e-e-e-esh! ...Jim Thompson

Your explanation of how the loop gain/phase affects the oscillation? Yes, I missed it. Please explain.

Sure. I've met a few like that. I've even met a couple of people who say that sort of thing from time to time, and happen to get it right.

Your faith in your own judgement is touching, but misplaced.

The MC4024/MC4044 pair were useful when they first appeared, and I used them back in 1972. That they were both TTL-compatible didn't make them any easier to use. The 4046 killed any market they might have had

- the 4046 VCO wasn't as fast, and none of the modern variants can get up to 30MHz either, but market doesn't seem to have been all that enthusiastic about running the VCO that fast.

I misspoke, the driver runs _off_ a 9V supply see the DP8392A data sheet it seems to turn most of the input power into heat.
