[time-nuts] Cathodeon TCXOs??

[Alan Melia]

Hi I wonder if anyone still has a datasheet/catalogue of Cathodeon products.
This firm made crystals and oscillators and filters in the 1980 and 90s in
Cambridge, England. (It is only 50 miles up the raod but I have not been
able to find anyone who still has any knowledge of the products.)

The units are FS5980/01  10MHz
                    FS5951/31    5MHz
I think the the 10MHz may be a TCXO,VCTCXO or even an OCXO, but  the 5MHz
does not have enough pins to be other than a TCXO. The spec would be useful
(I think I have that from a previous query) but a pin-out is the vital
information because none of the pins is common to the case, so it is
difficult to work out the connections with an ohm-meter.

Thanks
