Hello all,
i got an object that seems to be a TXCO but i need some info about how
to use it.
The manufacturer is Siemens, the device looks like e black
cilinder,diameter about 6.5 cm and 9 cm high, with a 9 poles circular
male connector (similar to octal type) on the bottom and on the top the
following inscription:

"Siemens
Schwingquarz-thermostat
4,000000 Mhz
70° C   20V 14W
Q91502-A4000-E-1".

If there is someone reading the reflector that knows  the output
connector pin map please tell me !

Thanks in advance
