Abstract
UN CIRCUITO DE SINCRONIZACION PARA SINCRONIZAR UNA SEÑAL DE ENTRADA DIGITAL (DIN) CON UNA SEÑAL DE RELOJ (CK1) INCLUYE UN CIRCUITO DE DETECCION (DC) QUE COMPRUEBA SI UNA MUESTRA PRESENTE (SA) DE UNA SEÑAL DE RELOJ (CK3) QUE SE ESTA SINCRONIZANDO CON LA SEÑAL DE ENTRADA DIGITAL, ES IGUAL A LA MUESTRA ANTERIOR (SB), AMBAS MUESTRAS SE HAN TOMADO A UN INTERVALO IGUAL AL PERIODO (T) DE LA SEÑAL DE RELOJ SINCRONIZADA CON LA SEÑAL DE SALIDA. CUANDO LAS MUESTRAS DIFIEREN, EL CIRCUITO DE DETECCION GENERA UNA SEÑAL DE AJUSTE DE FASE (CLR), QUE ACTIVA UN CIRCUITO DE AJUSTE DE FASE (PAC) PARA ASEGURAR UNA VUELTA AL SINCRONISMO DESFASANDO LA SEÑAL (ES) QUE CONTROLA EL MUESTREO DE LA SEÑAL DE ENTRADA DIGITAL.
