P. 104
Equation (3.65) is valid for any type of loop filter. For the lock time T , we obtain the same
L
approximation made for type 1 phase detector [Eq. (3.62)].
When we compare the lock range obtained for the EXOR phase detector with the lock range
obtained for the multiplier phase detector, we observe that Δω is larger by a factor of π/2 in
L
case of the EXOR.
