摘要

This work presents a pre-charge type DPLL that can be used as a clock recovery circuit in SDH/SONET communication protocols at 622 MHz. It is presented the phase/frequency detector which can operate equally at low and high frequencies. Each block of the DPLL is described, calculated and simulated. It is also presented the stability criteria and analysis of the DPLL and its final layout. The main feature of this work is the quick synchronization time of the DPLL due to the inclusion of an initialization circuit.
