Abstract

DIVISOR PROGRAMABLE DE GRAN VELOCIDAD, PARTICULARMENTE DIVISOR DE FRECUENCIA QUE INCLUYE LA COMBINACION DE UN PREGRADUADOR (110) DE MODULO FIJO Y UN DIVISOR PROGRAMABLE (120, 130, 140, 150, 160), EN LA CUAL EL PREGRADUADOR PROPORCIONA MAS DE UNA SOLA FAE DE RELOJ DE RITMO AL DIVISOR PROGRAMABLE Y EL DIVISOR PROGRAMABLE UTILIZA LAS FASES MULTIPLES DE RELOJ PARA PERMITIR EL FUNCIONAMIENTO EN UNA MODALIDAD VERDADERA DE ENTEROS Y FRACCIONARIOS. LACOMBINACION GLOBAL DEL PREGRADUADOR Y EL DIVISOR PROGRAMABLE FUNCIONA COMO UN DIVISOR PROGRAMABLE PARA EL CUAL EL INCREMENTO MINIMO EN EL MODULO GLOBAL DEL DIVISOR ES MENOR QUE EN EL MODULO DEL PREGRADUADOR, PERO LA MAXIMA FRENCUENCIA DE RELOJ UTILIZABLE ES LA MAXIMA DE RELOJ DEL PREGRADUADOR. APLICACION EN TEMPORIZADORES DE PRECISION Y SINTETIZADORES DE FRECUENCIA.
