Base band signal processing chip

Abstract

A base-band signal processing chip includes a plurality of input-output terminals, an analog signal processing module, a base-band signal generating module, a base-band signal processing module, a control module and a clock module, wherein the analog signal processing module is mainly used for preprocessing, including the analog-digital conversion of, signals to be emitted and the base-band signals to be processed, and the base-band signal generating module processes the signals to be emitted to generate the corresponding base-band signals, and the base-band signal processing module processes the base-band signals to be processed to drive the subsequent parts, and the control module implements the control of encryption and decryption and mute of processed signals by controlling the base-band signal generating module and a base-band signal processing module, and meanwhile the clock module provides the working-required clock to the control module, thus integrating the processing and controlling of analog-signal band-base signals on a single chip.

Description

technical field [0001] The invention relates to a baseband signal processing chip. Background technique [0002] The walkie-talkie is a point-to-point or point-to-group communication device that does not require any base station, and the spectrum it uses is also free, so walkie-talkie users can enjoy the convenience of free communication with anyone in the group anytime, anywhere, which leads to The application of walkie-talkies is extremely extensive. However, the currently used walkie-talkies are based on discrete components and small-scale integrated circuits, so the formed walkie-talkies often have 300-400 components, resulting in a large volume of the walkie-talkie, and high component and production costs, which is not conducive to the further popularization of the walkie-talkie. Therefore, How to solve many problems that existing walkie-talkies exist has become a technical problem urgently to be solved by those skilled in the art. Contents of the invention [0003]...
