I think that the TBolt's schematic(s) are sort of HolyGrail for

They are pretty simple, so I am amazed that there has been no major
attempt to reverse engineer them. The GPS front-end chip I haven't
been able to find a datasheet for, and then the CPU/GPS-baseband chip
seems to be an ASIC, but most pins should be fairly simple to explain.
I have only one Tbolt, so I don't want to put that into pieces (again).
Cheers,

I have 4, two of which have had the low phase noise OCXO removed for use
in a PN interferometer.
The TBolt output buffer has relatively high phase noise.
