The UCCM modules came from Samsung WiMAX radio systems. It looks like they OEM'd the boards from both Trimble and Symmetricom. "UCCM = Universal Core Clock Module" UCCM-P = "Universal Core Clock Module - Plus". I managed to find a system description document that mentions it two or three times. No details, though.

Does anyone know the origin of the "UCCM" designation for the Trimble
GPSDO boards recently popular here?

Is "UCCM" a valid model number, is it an acronym or is it something else?

I've packaged several of these Trimble boards and I've seen about four
others, none of which was marked "UCCM." I've seen one on-line picture
of a packaged board that shows a separate label with "UCCM" marked.

GPSCon already supports these "UCCM" boards and the next release of Lady
Heather is expected to support them also, so there is some acceptance of
this "UCCM" designation. But, what is the origin of this term and is it
valid?
