Title (EN) TIMING RECOVERY CIRCUIT
(FR) CIRCUIT DE RETABLISSEMENT DE SYNCHRONISATION
Abstract:
(EN) Prior art circuits for recovering timing information from baseband digital signals include a rectifier and a separate phase detector for controlling the phase of a phase-locked voltage-controlled oscillator. In the circuit described herein, an antiparallel diode pair (21) is used to perform the two functions of rectification and phase detection. The resulting timing circuit is, thereby, simplified.
(FR) Les circuits de l'art antérieur pour le rétablissement des informations de synchronisation à partir de signaux numériques de bandes de base comprennent un redresseur et un détecteur de phase séparés pour la commande de la phase d'un oscillateur à verrouillage de phase commandé en tension. Dans le circuit ci-décrit, une paire de diodes anti-parallèles (21) est utilisée pour exécuter les deux fonctions de redressement et de détection de phase. Le circuit de synchronisation résultant se trouve ainsi simplifié.
