Title (EN) PHASE LOCKED LOOP, PHASE LOCKED LOOP ARRANGEMENT, TRANSMITTER AND RECEIVER AND METHOD FOR PROVIDING AN OSCILLATOR SIGNAL
(FR) BOUCLE À VERROUILLAGE DE PHASE, AGENCEMENT DE BOUCLE À VERROUILLAGE DE PHASE, ÉMETTEUR ET RÉCEPTEUR, ET PROCÉDÉ POUR FOURNIR UN SIGNAL D'OSCILLATEUR
Abstract:
(EN) A phase locked loop, for a particularly in a beamforming system comprises a loop filter (1) to provide a control signal (FC) to a controllable oscillator (2); a frequency divider (3) configured to provide a first feedback signal (FB) and a second feedback signal (FBD) in response to an oscillator signal (FO), wherein the second feedback signal (FBD) is delayed with respect to the first feedback signal (FB). An interpolator is configured to receive the first and the second feedback signal (FB) and to provide an interpolated signal thereof between the first and second feedback signal and in response to a phase control word. A comparator path is configured to receive the interpolated signal and to provide a respective signal to the loop filter (1) in response to a phase deviation between a common reference signal (FR) and the interpolated signal.
(FR) L'invention concerne une boucle à verrouillage de phase, destinée en particulier à être utilisée dans un système de conformation de faisceau et comportant un filtre (1) à boucle servant à fournir un signal de commande (FC) à un oscillateur commandable (2); un diviseur (3) de fréquence configuré pour fournir un premier signal de réaction (FB) et un deuxième signal de réaction (FBD) en réponse à un signal d'oscillateur (FO), le deuxième signal de réaction (FBD) étant retardé par rapport au premier signal de réaction (FB). Un interpolateur est configuré pour recevoir le premier et le deuxième signal de réaction (FB) et pour fournir un signal interpolé de celui-ci entre le premier et le deuxième signal de réaction et en réponse à un mot de commande de phase. Un chemin de comparateur est configuré pour recevoir le signal interpolé et pour fournir un signal respectif au filtre (1) à boucle en réponse à un écart de phase entre un signal commun de référence (FR) et le signal interpolé.
