[time-nuts] 100 MHz VCXOs
All: Anybody have a DATA SHEET on the Wenzel VCXO's mentioned here and being sold on ebay? I went to the Wenzel site and they say oscillators in that part number series are proprietary, you must contact them for additional information. I bought one, it got here REALLY quick, and was hoping to file some reference data Thanks, Jim wb4...@amsat.org --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ___ 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] 100 MHz VCXOs
Hi Those OCXO’s were made to the spec’s of an OEM customer. The spec’s are owned by that customer and can not be released without authorization from them. Anybody who wants to stay in the business would be a bit crazy to release somebody else’s intelectual property to the public. That’s not an uncommon issue with surplus OCXO”s. Rouglly 99.9% of them are built to customer spec.

There was a special series of part numbers of the form 5082-5XXX that never appeared in the catalog. I remember I was working on a step recovery diode multiplier and was trying to reverse engineer various multipliers that were designed into commercial equipment. I got the HP part number of the diode which was of the form 5082-5XXX from the manual and found out that there was no data available on these part numbers in the HP internal system. I called the Microwave Semiconductor Division and got the story Bob gave about OEM spec's. I said, sure I understand that, but I work for HP. I was told that you have to work for MSD, not just HP to get access to this information, and in any event, they would NOT sell us these diodes, even as an internal transfer.

Once upon a time, I worked for a Chicago based company that made both semiconductors and OCXO’s. CTS Knights had a custom OCXO controller IC tooled with the semi side of the business. There was nothing anybody could do to get anywhere near that IC. They would not even admit that they made the part, despite the *very* familiar logo on the can of the part ….
