Abstract

LA COMUNICACION DE INFORMACION DIGITAL A ALTA VELOCIDAD SE CONSIGUE UTILIZANDO UN FORMATO DE TRANSMISION ANALOGICA. UN TRANSMISOR QUE RECIBE DATOS DIGITALES EN PALABRAS MULTIBIT EN PARALELO CONVIERTE PALABRAS DIGITALES EN CICLOS DE RELOJ DE CONVERSION EN UNA SEÑAL ANALOGICA UNICA RELATIVA A UN NIVEL DE CC. EL TRANSMISOR INCLUYE TAMBIEN UN GENERADOR DE IMPULSOS DE REFERENCIA QUE COMBINA UN IMPULSO DE REFERENCIA CON LOS NIVELES ANALOGICOS GENERADOS POR EL CONVERSOR, PARA FORMAR UNA SALIDA ANALOGICA PARA SU TRANSMISION AL RECEPTOR. EL RECEPTOR INCLUYE UN DETECTOR QUE RECIBE LA SALIDA ANALOGICA. EN RESPUESTA AL IMPULSO DE REFERENCIA, EL RECEPTOR GENERA UNA SEÑAL DE RELOJ DE RECUPERACION. UN CONVERSOR INSTANTANEO DE ANALOGICO A DIGITAL CONVIERTE LOS NIVELES ANALOGICOS DE LA SALIDA ANALOGICA EN SALIDAS DIGITALES MULTIBIT. LAS PALABRAS MULTIBIT EN PARALELO SE REGENERAN EN CICLOS DE RELOJ DE RECUPERACION A PARTIR DEL MUESTREADO DE LA SALIDA DIGITAL MULTIBIT UNA VEZ POR CICLO. DE ESTA FORMA, UTILIZANDO UNOS SISTEMAS DE DIGITAL A ANALOGICO A DIGITAL, SE CONSIGUEN VELOCIDADES DE TRANSMISION DE BITS EFECTIVAS, QUE SON SUPERIORES A LAS VELOCIDAD ES DE CONMUTACION DEL TRANSMISOR Y DEL RECEPTOR
