Hi Scott,
be careful, 5.5V at 50% duty cycle is about 21.5dBm into 50 Ohms.
The Fury will probably not be damaged, but it is outside of it's spec, so
you are overdriving it.
3.3V CMOS outputs are much preferred if a sine output is not available.
A simple solution could be a resistive, or capacitive divider, say two 220pF
caps in series with the center tap going into the Fury GPSDO.
bye,
Said
