The invention discloses a
digital interface radio frequency chip and an implementation method thereof. The
digital interface radio frequency chip comprises a receiving antenna, a
radio frequency analog front-end subsystem and an analog
baseband subsystem, wherein the analog
baseband subsystem comprises an
oversampling analog-to-
digital converter, an internal
clock generating module, a
digital signal processor and a
multiplexing parallel module, an output end of the receiving antenna is connected with an input end of the
multiplexing parallel module through the radio frequency analog front-end subsystem, the
oversampling analog-to-
digital converter and the
digital signal processor sequentially, and an output end of the internal
clock generating module is connected with a
clock input end of the
oversampling analog-to-
digital converter and a clock input end of the
multiplexing parallel module respectively. According to the
digital interface radio frequency
chip, clocks generated inside the radio frequency chip serve as reference clocks, so that the
correctness of the
baseband chip data collection can be guaranteed; and no complex first-in first-out (FIFO) structure is required, the structure is simple, the integration is easy, and the cost and the
power consumption are reduced. The digital interface radio frequency chip and the implementation method thereof are widely applied in the technical field of communications.
