Hi Chances of finding that in distribution are near zero. Best approach is to find a part with the same pin out / frequency / supply / EFC / stability on an auction site. Since it's a 5V / 14 pin DIP that should be possible.
Another simple fix would be a distributor stock miniature VCTCXO and a small carrier board.

It's been clocked by an external 10 Mhz source for the whole time I've owned it so I wanted to verify that the internal VCTCXO was still up to snuff. after CALing the internal reference I set it up to monitor the output from my Tbolt and it started drifting. the drift was bad enough that I started to investigate. The internal reference was wandering around by as much as 60 Hz over the course of 10 min. monitoring the EFC voltage at R343 indicated that there was not so much as a mV change during that time. this has led me to the conclusion that the XO on the board is suspect. The MtronPTI K1601TE that's on the board is EOL and the replacements don't seem to be stocked at any of the disti's listed on Mtron's website that I've checked so far. I've not started the search for , Does anyone have any suggestions for replacements? --Eric _________________________________________ Eric Garner _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
