Surplus OXCOs needed

[Bob Armstrong]

I need a small quantity (say, a dozen or so) oven controlled crystal
oscillators (OXCOs), but I can't afford the $150-$200 price for new
ones. Pretty much any frequency from about 4Mhz to 20Mhz would be OK.
Does anybody know of any source for surplus ones?

Thanks,
Bob Armstrong

Feed OXCO to Ebay.

If that isn't good enough, take the part numbers you get and
feed them to google.

Bob,

I've seen 10 MHz OCXOs on eBay for $50 or so.

Have you tried to contact any of the major suppliers if they have
something in stock you could use?
Sometimes orders get cancelled or customers go bankrupt and the OCXOs
may be available cheap if your requirements are not exotic.
Especially if you can accept ANY freq, they can sell you stock parts
they could senn to noone else (means cheap)
Just tell them your requirements regarding supply voltage, temp range,
dF/temp, dF/dSupply, pulling requirements (v-range, ppm-range),
calibration tolerance, aging/month or year.
If you can take anything between 4 and 20 MHz, can supply 12V or 5V
with 5% tolerance with enough current, yout temp range does not exceed
0° to 60° and pulling of 1-2ppm is enough, you should have no problem
at all finding something from stock.

They used to supply small quantities also

I meant OCXO - sorry about that; just a typo.

Feed OXCO to Ebay.

Been there, done that. I need a dozen or so that are the same, and
eBay is more of a one of a kind place. These muRata parts are nice:


http://cgi.ebay.com/10MHz-OCXO-crys...ryZ25399QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

and it appears that the seller has several of them (be has multiple
listings for the same part). BUT, these parts are clipped sine wave
output, and I need TTL/CMOS/HCMOS outputs.

This one is interesting too

http://cgi.ebay.com/Vectron-Militar...578472361QQcategoryZ25399QQrdZ1QQcmdZViewItem

BUT, if you look up the datasheet for it, the frequency stability is
several PPM. I don't know what it's for, but it's not an OCXO.

If that isn't good enough, take the part numbers you get

No need - I've been browsing the D-K and Mouser catalogs for hours.
Something like the Fox FTS501AH would be perfect - oven controlled,
fits on a PC board (14 pin DIP outline), 5V HCMOS, 250 PPB tempco, BUT
at $120 each. Mouser calls this a TCXO in their catalog, but I think
that's a mistake.

D-K has the Connor-Winfield OFC5DJ3BS - same basic idea, but SMT.
$213 each. Eeeek!

and feed them to google.

Tried that - you'll find data sheets, product announcements,
distributers, and jobbers like Parts Miner. If there are any cheap
surplus ones, I can't find 'em.

Thanks,
Bob
