Abstract

LOS CIRCUITOS DE REGULACION PLL EN OSCILADORES HORIZONTALES DEBEN TENER EN ESTADO BLOQUEADO UNA VELOCIDAD DE REGULACION REDUCIDA, PARA QUE NO SE GENERE EL EFECTO JITTER DEBIDO A SEÑALES DE ENTRADA CON PRESENCIA DE RUIDOS. DEBIDO A LA DESFAVORABLE RELACION DE IMPULSOS ENTRE LA LONGITUD DEL IMPULSO SINCRONICO Y LA DURACION DE LINEA (4,7:64) LA VELOCIDAD DE REGULACION A GRANDES DIFERENCIAS DE FASE DE LAS SEÑALES PLL ES SOLO PEQUEÑA Y, P.EJ. AL CONMUTAR ENTRE DIVERSAS FUENTES DE PROGRAMA DE UN RECEPTOR DE TELEVISION, DURA RELATIVAMENTE MUCHO TIEMPO (ALGUNAS SEMI-IMAGENES), HASTA QUE LA SINCRONIZACION DE LINEAS VUELVE A ESTAR EN ESTADO BLOQUEADO. MEDIANTE LA EVALUACION LOGICA DE UN IMPULSO ADICIONAL PRESENTE EN EL RECEPTOR DE TELEVISION O FACILMENTE GENERABLE, LA SEÑAL DE MANDO PARA EL VCO PUEDE CONMUTARSE EN LA PLL, EN CASO DE GRANDES DESVIACIONES DE FASE, P.EJ. A UNA CORRIENTE DE CONTROL CUADRUPLE. PARA REGULACIONES PLL CON SEÑALES DE ENTRADA QUE NO TIENEN UNA RELACION DE IMPULSOS DE 50:50.
