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'

Hi
I’d bet it’s an inventory label put on by their customer. If so a good bet
would be something
like China Unicom.

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 ti
I was trying to guess what acronym (or backronym) UCCM might stand for.
Then I did an E-bay search and found all the PC boards with "94V-0" in
their part numbers for sale E-bay. Ha! Literally thousands of hits.

Well, that actually helped a little. I dug a little further into the system
documentation, and while there is only a smattering of information on the UCCM
itself, I was able to find that the alarm parameters for them dictate a
5.2-5.8v supply range, so THAT finally definitively answers one of th
12 matches
