Phase domain operation of PLL

Hello Everyone,

What is phase domain operation of PLL ?

Thanks

I think it is the range of angles in which the responce of the pll (phase frequency discriminator) is linear without dead zone.

As indicated by the name "PLL" - this loop reacts upon phase changes of an incoming signal.
For this reason, the linear PLL model (in-lock condition) is a feedback loop, which has a phase information PHI(s) as an input as well as an output.
Consequently, the corresponding transfer function is in the phase domain T(s)= PHIout(s)/PHIin(s)
