You always, by definition, get 360 degrees around an analogue  
oscillator.  The question comes down to how you split that 360 up.   
If you have equal phase shifts, as in my case, then yes you would get  
360/N.

Alternatively, throw in an inverter (fixed 180 degrees) and you'll  
get 0, 60, 120, 180 outputs.

Cheers,
Neil
