Abstract

The invention relates to a radio-frequency chip interface circuit. The interface circuit comprises: a data transceiver module for receiving or transmitting data; a DMA data transmission engine which is connected with the data transceiver module for data transmission; an event list control unit which is connected with the data transceiver module for completing the trigger operation control of events; and a sleep-awaken switching unit which is connected with the event list control unit for completing the fast and slow clock frequency switching in the sleep and awaken processes. According to the invention, by improving the interface of the data transceiver module, the data communication rate between the interface circuit and a radio-frequency chip can be improved, and by adding the sleep-awaken switching function, the overall power consumption of the system can be reduced.

Description

technical field [0001] The invention relates to integrated circuit technology, in particular to a radio frequency chip interface circuit. Background technique [0002] The radio frequency chip interface circuit is an interface circuit that connects the baseband chip with the off-chip radio frequency chip for data transmission and reception interaction. [0003] The radio frequency chip interface circuit in the prior art usually has only one data interface to communicate with the radio frequency chip, and can only support one radio frequency antenna, and can only send 1 bit of data per clock cycle, its data transmission rate is low, and there is only one The 32-bit data bus has a small data throughput. In addition, the overall power consumption of the radio frequency chip interface circuit in the prior art is relatively large. Contents of the invention [0004] The object of the present invention is to provide a radio frequency chip interface circuit with high transmissio...
