Embodiment Construction

[0045] Under the trend of high integration of existing electronic products, there are more and more applications of signal multiplexing technology in electronic products. However, it is precisely because of the high integration of electronic products that the space constraints of products are becoming larger and larger. When realizing the signal multiplexing function, it is difficult to meet the space restriction requirements of the product. The inventor found through investigation that the main reason that the existing technology is difficult to meet the space restriction requirements is that multiple signal lines are used to realize the signal multiplexing function, which leads to the connector The PIN pin is large in size and may not be installed between the boards. For example, it is difficult to install a larger connector between the power card and the main control card.

[0046] The defects in the above solutions in the prior art are the results of the inventors' practice an...

Abstract

The embodiment of the invention relates to the technical field of the electronic product, specifically, relates to a signal multiplexing circuit and method. The signal multiplexing circuit comprises an insertion detection unit, an insertion unit and a low-power consumption mode enabling unit; the insertion detection unit and the low-power consumption mode enabling unit are respectively connected with the insertion unit; the insertion detection is used for receiving a multiplexing signal sent by the insertion unit, and comparing the acquired set voltage with the voltage of the multiplexing voltage to acquire a comparison result, and inputting the corresponding level signal to a switch according to the comparison result; the switch is used for adjusting the own working state according to thelevel signal so as to realize the output of different detection signals. The low-power consumption mode enabling unit is used for adjusting the multiplexing signal; the insertion unit is used for controlling the working state on the external boosting line according to the adjusted multiplexing signal. The signal multiplexing circuit can satisfy the space limitation requirement of the product in the premise of realizing the signal multiplexing function.
