Anyone who needs an app note to tell him/her every little thing is lost anyway. App notes advise, they don't teach. If you need to be taught, get some background somewhere else.

He may be writing the app note but he's not developing and testing circuits that go into the app note unless the manufacturer is populated with maroons like TI. Their app notes read like a lesson from Romper Room.
God wouldn't have it any other way; you're just along for the ride.
I worked for a guy once who did circuit design by tossing together a salad of circuits from data sheets, with no attention paid to grounding or impedance matching issues (or for keeping quiet circuits away from noisy ones, for that matter).
"Seems to work" was a pretty good summation of what he got, and was part of why he hired me.

will do that. However I believe there's now a 12000 series ECL/PECL equivalent that will go even faster. ...Jim Thompson

I love to cook with wine. Sometimes I even put it in the food.
Thanks Fred, (and others) I think mini circuits may be the answer. I'll order one to play with.

OK I think I should be able to make the VCO control voltage stable at the mV level. I don't really need such a big range. But if I go the minicircuits route I'm stuck with whatever varactor they put in there.

OK Thanks Jim, I think I may spend money and save time by just getting a minicircuits thing.
George H.
Certainly. Hard to beat someone putting it all in one package for you.

Cleaning it up with an RC lowpass isn't very hard--that's what's inside the MCL VCO.
