Re: [time-nuts] STEL 1173 datasheet
I can now see that a conversion between the dip and PLCC would be do-able but as mentioned earlier nasty. Don't they make socket converters? I would think that would be the easiest way to go assuming the pinouts would be correct. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] STEL 1173 datasheet
yes normally plcc to dip but not the other way around. (cause who would ever need that) That said the plcc and dip pin out is not a straight 1 for 1 and that makes things a bit messy. That would not stop me from doing it though. That is making a frankenstein adapter.

Re: [time-nuts] STEL 1173 datasheet
I've been looking for some kind of converter but, so far, I've come up empty. A converter to allow a PLCC44 to be used in place of a DIP is easy to find, but a converter to allow a DIP to be used in place of a PLCC44 is rare, at best. It also occurred to me that signal fidelity (crosstalk, ringing, etc.) could be an issue in such a conversion. The 4065C manual says that the synthesizer clock is 45 MHz and the output of the 1173 drives an AD9713BAP D/A converter to generate the 12.6 MHz sine wave. Signal fidelity could also be an issue with an FPGA replacement for the 1173. The FPGA would be on a board that would have to be connected to the original location with a cable around 10 cm. in length.

Re: [time-nuts] STEL 1173 datasheet
Wow at $155 or $125 + $65 for a stel replacement chip. Like the concept they have of allowing you to rewire the pins and frankly it would appear the $125 is a cleaner fit if it can be offset in the CS ref. But hey its not my project so will watch from the side lines.

Re: [time-nuts] STEL 1173 datasheet
Now that looks promising! The show-stopper problem with adapters like Jason found is size. There's only about 20 mm between the circuit board and the top of the case. I can imagine soldering this plug to a board that had either the DIP chip or a ribbon cable to connect it to an FPGA board. I'd have to solder a socket onto the original board to use this, but that might be possible. There's one surface-mount capacitor that's close enough to the 1173 that it could prevent the installation of a socket. Thanks for the info, Bob!

Re: [time-nuts] STEL 1173 datasheet
It's starting to add up, isn't it? The only reason I'm considering it is because I was able to confirm that the Cs tube is alive. If I can get it working for a couple of hundred dollars and some time I think it's a worthwhile project and as Bert Kehren mentioned, I'm not the only one with a dead 1173 chip so others might benefit.

Actually, this is the trimcap which sets the VCXO mid frequency. Good that you found it and reported on it here. The said trimpot was originally set to about 1 o'clock and fixed by lacquer.

Re: [time-nuts] Battery Part # For Motorola M12+T ???
For interest, the prefix refers to the chemistry and the numbers describe the nominal dimensions in mm. So: ML = Manganese Lithium (rechargeable) (3V) MT = Manganese titanium lithium (rechargeable) (1.5V) and 621 = 6.8mm diam x 2.1mm thick. This system is reasonably consistent for coin cells from all but US manufactures. ian Date: Wed, 7 May 2014 15:53:52 +0200 From: mike cook michael.c...@sfr.fr To: Discussion of precise time and frequency measurement time-nuts@febo.com Subject: Re: [time-nuts] Battery Part # For Motorola M12+T ???
