Re: Quartz oscillator

Hello,

I'm working on a PCB on which I have to put a 17,72 (4fsc)
oscillator.
I have one unused schmitt trigger inverting gate. Can it be used with
a crystal for making an oscillator (in order to keep it cheap and
compact), or do I have to use a "regular" gate ?

If it's an RF or video application, I'd avoid it.
A company I worked for spec'd a Schmitt by mistake
in a clock circuit. Everything functioned, but
jitter in the clock showed up as spurious noise
all across the spectrum. The techs trying to
troubleshoot the things were almost in open revolt
before it was dealt with.

Maybe you can get away with a single 7404-type
inverter in a SOT-353 package? They're small &
cheap. Try a Digikey search on "sot 353".
