Abstract
UN DESINCRONIZADOR (20) PARA DESINCRONIZAR DATOS ALMACENADOS DENTRO DE ENVOLTURAS DE CARGA SINCRONA DE UN PROTOCOLO DE COMUNICACION SINCRONA TAL COMO SONET (RED OPTICA SINCRONA), PREVE SUAVIZA LA SEÑAL DE RELOJ PERIODICAMENTE DISCONTINUA ASOCIADA CON TAL DATO DESPUES DE QUE EL PROTOCOLO DE COMUNICACION SINCRONO AEREO HAYA SIDO ELIMINADO. EL DESINCRONIZADOR ACOMODA PARA DESPLAZAMIENTO EN LA POSICION DE LA ENVOLTURA DE CARGA Y ASI ESOS DATOS DENTRO DEL MARCO DE COMUNICACION SINCRONA ASI COMO DENTRO AJUSTE DENTRO DE LOS DATOS EN SI DEBIDO A INFORMACION DE MATERIAL DE . EL DESINCRONIZADOR UTILIZA UN FILTRO DE FUGA 826) QUE TIENE UNA RAMA LINEAL (54) Y UNA RAMA INTEGRADOR (56), TENIENDO AMBAS RAMAS FACTORES AJUSTABLES (61, 63, 65, 88, 90,93, 95, 100, 102, 105) RESPECTO DE SU OPERACION, DONDE LOS FACTORES AJUSTABLES SE ELIGEN DEPENDIENDO DE LOS VALORES UMBRAL (86, 87, 89, 62) QUE A SU VEZ ESTAN BASADOS EN LA DIFERENCIA ENTRE LA DIRECCION EXRITA MEDIA Y LA DIRECCION LEIDA PARA EL ALMACEN ELASTICOASOCIADO (22) DENTRO DEL CUAL LOS DATOS ENTRANTES ELIMINADOS DEL MARCO DEL SISTEMA DE COMUNICACION SINCRONO SE ALMACENAN TEMPORALMENTE. EL FILTRO DE FUGA (26) FORMA PARTE DE UN BUCLE CERRADO DE FASE QUE A SU VEZ AJUSTA LA FRECUENCIA DE RELOJ LEIDA (46) DE MANERA A MINIMIZAR LA INUNDACION LA FALTA DE FLUJO DEL ALMACEN ELASTICO MIENTRAS QUE MINIMIZA SIMULTANEAMENTE LA VELOCIDAD DE CAMBIO DE LA VELOCIDAD DE RELOJ LEIDO DE MANERA A LIMITAR EL TEMBLOR. UN APARATO DE RECUPERACION DE FALLA FORMA PARTE DEL DESINCRONIZADOR PARA PERMITIR LOS FACTORES DE GANANCIA ALTA DE RELOJ RAPIDO (67, 97, 107) PARA AJUSTAR RAPIDAMENTE EL RELOJ DE LECTURA CUANDO OCURRE LA FALTA DE FLUJO O INUNDACION DE ALMACEN ELASTICO. EL FACTOR DE GANANCIA ASOCIADO A TANTO LA RAMA LINEAL COMO LA RAMA INTEGRADOR QUE PUEDE SER MODIFICADA PARA ENCONTRAR LA NECESIDAD DE TEMBLOR PARTICULAR DE UN SISTEMA DE COMUNICACION SINCRONO PARTICULAR. U APARATO DE CALCULO (82) REALIZA CALCULOS PARA GENERAR EL VALOR DE SALIDA DEL FILTRO DE FUGA QUE UTILIZA UN NUMERO REDUCIDO DE PUERTAS LOGICAS PARA LA IMPLEMENTACION ASIC.
