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

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. Tim N3QE On Mon, Dec 5, 2016 at 7:42 AM, Bob Camp wrote: > Hi > >

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

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. Bob > On Dec 4, 2016, at 5:50 PM, Larry McDavid wrote: > > Does anyone know the origin of the "UCCM" designation for the Trimble GPSDO > boards recently

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."
