Abstract
Un montaje de reloj patrón mejorado mediante el cual se puede disponer de un número de señales de reloj de salida valiéndose de por lo menos dos bucles de enganche de fase cada uno de los cuales está controlado por una fuente de oscilación exterior y suministrando en sus salidas dichas señales de reloj de salida, caracterizado porque por lo menos para uno (PLL2, PLL3) de dichos bucles de enganche de fase (PLL1, PLL2, PLL3) dicha fuente de oscilación exterior (f1) es la salida de otro (PLL1) de dichos bucles de enganche de fase.
