Question about cristal oscillator

do you want to adjust it by exchanging the crystal with a different one? Crystal oscilators are basically fixed to the frequency of the crystal. (adjustemnt is maybe +/- 1% if you push them real hard)

Crystal oscilators are typically low jitter (especially if given a stable power supply etc), that design was done to get the crystals tp produce overtones, running in overtone mode may give significant jitter.

the web site also says you get a chose of F 2F and 3F. however you choose F only at-most only one of (F,2F,3F) will be in the 10-12Mhz range.

if you want a low jitter, tunable, oascillator with an adjustment range that covers 10 to 12Mhz some sort of L-C oscillator may be a better choice.

Possibly followed by a sharp pass-band filter to filter out jitter.

That's true but it won't pull the frequency very far away from the crystal design frequency. Nothing like 1MHz.

Hello

I need a frequency of 11.2896 mhz, so I should try to find a crystal at this frequency but there is nothing like this arround here.

Thank

Didn't look very hard did you ? Ever heard of Google ? I entered "11.2896 mhz" and the first hit was this.

Seems to include the oscillator too.

Yes!

You may have to do mail-order.

these guys have a bunch in that frequency,

not being a fan of SMT I'd get the top one.

The fact is that the frequency he wants is READILY AVAILABLE !

Graham

Sure. But was that because they stock 11.2896 MHz parts or because they pay Google to tell you: "When ordered by thousands, we will supply any frequency in that range" ? :-)

Hello everybody

I know Google and Mouser, but last time I've order by mail few electronics parts by mail (nothing of heavy weight) it cost me $35 for shipping only, that was too much for my low budget !!

So I am not very interest to do anymore mail ordering.

Thank

Bye

Try Electrosonic

They're a Canadian electronic distributor, and have an office in Ottawa, so you may be able to pick up the parts there, and avoid shipping charges (but they may still have a minimum order.)

Where the heck DO you expect to get them then ?
