[time-nuts] SE880 GPSDO

[Ilia Platone]

Hi Attila,

This is a hobby project, by now, but if these devices can be versatile 
and small, they could be used for a work project. till now, hobby and 
open source.
I am stuck at the timing issues. After finding a suitable stable clock, 
on multiple and independent boards, for 8 hours, I'll begin designing 
the software of these.

I must print each photon event captured by an APD at the focus of more 
telescopes, these events must be timestamped with an accuracy of 2.5ns, 
and the expected rate is lower than 10MHz, The overall capture runs will 
take about 4-5 hours, it depends on the object observed, after capturing 
I must compare the timestamps logs each other to find if are there 
common events/timestamps in the various fluxes. I need a stable clock to 
reduce the software needs, for example if the automated captures of each 
device ends withinone second each other I think it would be too much, 
but I am thinking I must be more flexible in the software side.

Regards,
Ilia.
