Abstract. Digital phase-synchronization systems with clock period interpolation effected by implementation of local generator operated in multiphase ring circuit and application of phase interpolation elements are considered. Diagrams of controllable delay element – ring generator unit – and phase interpolation element are presented. Principles of design of phase-synchronized interpolation devices with relay and sawtooth characteristics of phase comparison circuit are described.
Keywords: ring oscillator, pulse frequency, delay element, phase interpolation, Delay Lock Loop, Phase Lock Loop.
