NettetAn important point for PLLs is the large signal behaviour when the system is not in lock. When the PLL starts up, ϕ ref and ϕ out may be very different. We must make sure that the system is able to achieve lock. Another concern is whether the PLL will lock to a harmonic instead. The PLL with XOR based PD is not robust in this case.
