Abstract
PARA UNA INSTALACION DE DESCODIFICACION CMI Y DE RECUPERACION DEL RELOJ SE PROPONE UNA SOLUCION AMPLIAMENTE INTEGRABLE, QUE NO REQUIERE UN CIRCUITO INDEPENDIENTE PARA LA CORRECCION DE FASES Y PARA LA AMPLIFICACION Y QUE ADMITE UNA FLUCTUACION DE FASE EN TODO EL MARGEN DE FUNCIONAMIENTO. UN DESCODIFICADOR CMI (6,7,8) CONOCIDO SE COMBINA CON UNA INSTALACION DE RECUPERACION DEL RELOJ CON ELEMENTOS (6,10B,11B) CONOCIDOS Y CON ELEMENTOS (15,16B,17B) NUEVOS, QUE CONTIENE UN SISTEMA DE PUERTAS CAPAZ DE EXTRAER DE LA SEÑAL DE DATOS (D1) CON CODIFICACION CMI UNA CANTIDAD DE IMPULSOS DE RELOJ SUPERIOR A LA POSIBLE HASTA AHORA. CON EXCEPCION DE LOS ELEMENTOS DE RETARDO (6,15) Y DE UN CIRCUITO (12B) DE SELECCION DE LA FRECUENCIA DEL RELOJ, TODOS LOS ELEMENTOS SE HALLAN EN UN CIRCUITO INTEGRADO (18). IGUALMENTE CONTIENE TRANSFORMADORES (19,20,21,24,25) DEL NIVEL DE ENTRARA Y (22,23) DEL NIVEL DE SALIDA. LA INSTALACION SE PUEDE UTILIZAR EN EQUIPOS DIGITALES MULTIPLEX.
