Abstract
SINTETIZADOR DE FRECUENCIA CON BUCLE DE ENCLAVAMIENTO DE FASE DE DIVISION FRACCIONARIA MULTIPLE. COMPRENDE UN BUCLE UNICO DE ENGANCHE DE FASE PILOTADO POR UN RELOJ DE REFERENCIA (5) CONSTITUIDO POR UN OSCILADOR DE TENSION CONTROLADA (1), UN DIVISOR PROGRAMABLE (2) DE RANGO M VARIABLE, UN COMPARADOR DE FASE (3) Y UN FILTRO DE BUCLE (4). COMPRENDE TAMBIEN UN NUMERO DETERMINADO N DE ESTRUCTURAS DE DIVISION FRACCIONARIA (61 ... 6N) QUE REALIZAN CADA UNA DE ELLAS UN PASO DE FRECUENCIA PI (5X(1 FREF INFERIOR A LA FRECUENCIA DE REFERENCIA FREF. CADA ESTRUCTURA DE DIVISION FRACCIONARIA ESTA ACOPLADA EN PARALELO CON EL DIVISOR PROGRAMABLE (2) PARA AÑADIR AL RANGO DE DIVISION M UNOS INCREMENTOS FRACCIONARIOS PI DE TAL MANERA QUE LA RELACION ENTRE LA FRECUENCIA FVCO SUMINISTRADA POR EL OSCILADOR Y LA FRECUENCIA DE REFERENCIA FREF QUEDA DEFINIDA, EN FUNCION DE LOS INCREMENTOS PI, POR LA RELACION: FVCO = (M + (5_(11 PI) FREF EL INVENTO ES APLICABLE A CUALQUIER TIPO DE PRODUCTOS O SISTEMAS QUE NECESITENUN SINTETIZADOR, ESPECIALMENTE LOS SISTEMAS DE TRANSMISION CON EXCURSION DE FRECUENCIA.
