Abstract

UN CIRCUITO DE RECUPERACION SINCRONIZADA PARA UN RECEPTOR ATM. DERIVAR AUTOMATICAMENTE LA FRECUENCIA DE LA SEÑAL DE FUENTE QUE ES TRANSMITIDA POR LAS CELULAS ATM. UN SUBCIRCUITO (3,4,5) DETERMINA, EN LA BASE DE LA PROPORCION DE CELULAS, LA PROPORCION DE BIT NOMINAL DE LA SEÑAL DE FUENTE Y GENERA UNA SEÑAL SINCRONIZADA QUE TIENE UNA FRECUENCIA QUE ES CONSISTENTE CON LA MISMA. UN SEGUNDO SUBCIRCUITO (6,7,8,9,10) CORRIGE, EN PROPORCION A LA DIFERENCIA ENTRE LA PROPORCION DE BIT NOMINAL Y LA PROPORCION DE BIT DE MECANISMO ACTUAL, LA FRECUENCIA DE LA SEÑAL SINCRONIZADA GENERADA POR EL PRIMER SUBCIRCUITO.
