Don't recognise it. Obviously a telecoms system of some sort as -48VDC. From a Google search of the Trimble P/N I get some Chinese sites which you can glean something about an "ultra stable 10 MHz OCXO". I couldn't see a GPS module on the board, unless it's under the OCXO, but I doubt that.
Not sure what it's prime mission was for. My guess is cellular base station timing. Interested to see what else come up from others in the group.

There are some Trimble GPS receivers on eBay. They say "10Mhz 1pps" but they are not Thunderbolts. These are an A4 sized PCB, no enclosure. The seller says it takes 48VDC to run. Seems reasonable as there is a large DC/DC power converter in the board. Anyone know more? How to they compare to the Thunderbolt?
