Interface concept for the exchange of digital signals between an rf ic and a baseband ic

摘要

The invention relates to a circuit arrangement which is provided with an analog receive and transmit unit which includes at least one A/D converter 13 and at least one D/A converter 14 for the conversion of signals, and also with a digital processing unit for the processing of digital signals. The invention also relates to a user set for mobile communication which includes a circuit arrangement of this kind and to a method for the transmission of digital signals between an analog receive and transmit unit and a digital processing unit. A circuit arrangement is proposed in which a reliable transmission of digital signals between a digital processing unit and an analog receive and transmit unit can be realized with little effort; to this end, it is proposed to provide a storage unit 17 and an interface 18, 19 which are arranged for the exchange of digital signals between the analog receive and transmit unit and the digital processing unit, the signal or data exchange between the receive and transmit unit and the digital processing unit taking place exclusively in the transmit and receive gaps 43.
