[time-nuts] Some specs for MTI Millren 260 OXCOs
I contacted one of the MTI Milliren marketing guys a few days ago, and got some specs on the MTI model 260-0624C and 260-0544C OXCOs that are currently being sold on Ebay. the model 260-0624C is the one used in the Lucent /Symmetricom Z3810A systems. The model 260 is advertised as being close to a Rb in performance. This is all the data that he would give me since I wasn't the original customer for whom they were made. He also says these models are still in low volume production for the customers. 260-0624-C 5MHz, SC- cut crystal, 3rd overtone, 2E-10 over 0 to +75C Phase Noise spec: -100 @ 1Hz -130 @ 10Hz -145 @ 100Hz -150 @ 1KHz -155 @ 10KHz -155 @ 100KHz Also, the 260-0544C 260-0544-C 5 MHz, SC-cut crystal, 3rd overtone, 2E-10 over -30 to +70C Phase Noise spec: -110 @ 1Hz -140 @ 10Hz -150 @ 100Hz -157 @ 1KHz -160 @ 10KHz -160 @ 100KHz Cheers, Dave M ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] Some specs for MTI Millren 260 OXCOs
I got two used from China, they are six years old that is the standard time when the whole board get replaced in a cell phone base station they looking like the drawing in the data sheet except pin # 6 is missing but it is not connected anyway they have EFC pin and it is working I tried it with multi turn pot and the unit's own reference, the two kept the relative phase on the scope in ±10° for two days relative to each other. Does your unit has the pin -- which is not connected inside -- or the whole pin is missing? I f you want to open the can get some very thin beryllium-cooper foil and push it into the slot after you heated up the solder, that way you could separate the bottom plate and the can without doing major damage. 73 Alex On 10/22/2014 4:57 PM, Scott Newell wrote: At 04:20 PM 10/22/2014, Alexander Pummer wrote: may I get some copy of that datasheet?
