[time-nuts] FE-5680a DGND/GND separate?

I'm doing a simple PCB design for a breakout for the venerable FE-5680a, and I'm curious if there's any need/desire to separate out the GND/DGND (pins 2 and 5). In my test connection, I just used pin 2 for grounding the 15V supply, and pin 5 for everything else, but I figured they're connected internally to the oscillator, so I'm not sure the point. 

Is there any point in separating out those grounds?
