For a DIY project I'd like a 5.115 MHz OCXO. That weird-looking number
is half the basic 10.23 MHz GPS chip rate.
I realize it's trivial to create 5.115 MHz with a DDS chip, a function
generator, synthesizer, or even an aggressive phase microstepper. But in
this case, if possible, I'd prefer a simple single part; a plain old XO
or OCXO solution. Do any of you know where to get a 5.115 MHz crystal or
oscillator?
I'm pretty sure that I've seen one-off surplus 10.23 MHz or 5.115 MHz
OCXO on eBay but I never thought to bid on them because the frequency
was strange. If you saw one, and "bought before you thought", let me know.
Thanks,

I have seen 10.23 parts somewhere but can't remember the application.
If you can't track one down there's still a couple of reasonably priced
options for custom crystals, you can have them ground by a czech company,

IIRC someone has offered a 10.23 MHz variant of the 10811 some years ago
on the list.

Hi Tom,
I ran across one the other day, actually, looking for something else.
Surplus Sales of Nebraska has an HC-6 crystal as p/n (CRY) 005.115000
https://www.surplussales.com/Crystals/Crystals-3.html
Probably not exactly what You were looking for, but a start!

The first HP10544 I held in my hand was 10.23 MHz part of the GPS project.

Did the tbolt happen to use one? I've got a dead TAPR tbolt from a
lightning strike that I can rob from if needed.

I have two PIEZO Systems 10.230 oscillators similar tote one shown in the attachment. Mine are model number 2810007-2. They are supposed to be replacements for the HP oscillators. Take a look and see if they may be of help for you. If so, send me your mailing address and I will ship the two to you at no cost. I will include the interface printed circuit boards.
