The article describes a digital phase-locked loop (DPLL) system with even digitization and analog-to-digital convertion to a closed loop of PLL. On the basis of D-decomposition method the authors has defined domains of asymptotic stability of DPLL under consideration. Besides that they have detected a range of values of k1,k2,k3 parameters for which all the roots of characteristic equation of linear approximation of considered discrete nonlinear system are within complex plane unit circumference.
