Abstract

LA INTERFAZ DE COMUNICACION (2) PERMITE EL DIALOGO ENTRE UNA UNIDAD DE TRATAMIENTO (1A) Y UNA TARJETA INTELIGENTE QUE TIENE UNA UNIDAD DE TIEMPO ELEMENTAL DE TRANSMISION DE UN BIT (ETU) QUE VALEN [K/FS], Y QUE COMPRENDE UN MICROPROCESADOR Y UNA TERMINAL DE RELOJ (CK) PARA LA APLICACION DE UNA SEÑAL DE RELOJ EXTERNA DE FRECUENCIA (FS) QUE PERMITE LA FRECUENCIA OPERATIVA DEL MICROPROCESADOR DE LA TARJETA INTELIGENTE. LA INTERFAZ COMPRENDE: - UNA LINEA DE COMUNICACION EN SERIE (31) PARA EL INTERCAMBIO DE DATOS CON LA TARJETA INTELIGENTE, - MEDIOS DE SERIALIZACION DE LOS DATOS INTERCAMBIADOS EN LA LINEA DE COMUNICACION EN SERIE, - UNA SALIDA DE RELOJ (17) QUE ESTA DESTINADA A ESTAR CONECTADA AL TERMINAL DE RELOJ (CK) DE LA TARJETA INTELIGENTE Y POR LA CUAL TRANSITA LA PRIMERA SEÑAL DE RELOJ (12A) O UNA SEÑAL DE RELOJ SINCRONA CON ESTA PRIMERA SEÑAL DE RELOJ (12A) Y - MEDIOS (13, 14) QUE EMITEN A PARTIR DE LA PRIMERA SEÑAL DE RELOJ (12A), UNA SEGUNDA SEÑAL DE RELOJ (H) QUE PERMITE LA PUESTA EN MOVIMIENTO DE LOS MEDIOS DE SERIALIZACION (7, 8) Y QUE ES SINCRONA CON LA PRIMERA SEÑAL DE RELOJ (12A), CON UNA RELACION DE FRECUENCIAS ENTRE LA SEÑAL DE RELOJ QUE TRANSITA POR LA SALIDA DE RELOJ (17) Y LA SEGUNDA SEÑAL DE RELOJ (H) QUE ES IGUAL AL FACTOR (K).
