Title (EN) SPREAD SPECTRUM CLOCK GENERATOR HAVING AN ADJUSTABLE DELAY LINE
(FR) GENERATEUR D'HORLOGE A SPECTRE ETALE AYANT UNE LIGNE DE RETARD REGLABLE
Abstract:
(EN) A system and method are provided for performing a spread spectrum clock generation, where the system includes self-adjusting delay line configured to spread the spectrum of a fixed circuit using a fixed clock frequency and a delay circuit configured to generate an adjustment signal to the delay line by adding or subtracting an addition delay per cycle, therefore causing a shift in the output clock frequency, wherein the amount of shift is proportional to the rate of addition or subtraction of delay.
(FR) L'invention concerne un système et un procédé permettant de réaliser une génération d'horloge à spectre étalé. Le système comprend une ligne de retard autoréglable conçue pour étaler le spectre d'un circuit fixe au moyen d'une fréquence d'horloge fixe et un circuit de retard conçu pour générer un signal de réglage pour la ligne de retard en ajoutant ou en soustrayant un retard d'addition par cycle, entraînant un changement dans la fréquence d'horloge de sortie, le taux du changement étant proportionnel au taux d'addition ou de soustraction du retard.
