There was some PLL in a military radio that stayed in lock throughout 360
degrees of phase.. it was always comparing and adjusting, and it was running
accurate at extreme RF...

It would compare, one comparator ran into the count up input of a counter,
the other ran into the count down input.. It would constantly adjust and
either raise or lower the voltage to the vco..

I need to prod the engineer at work for more details on it..  It sounds very
cool though..
He spent about an hour explaining it to me a couple of weeks ago..
