Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0030] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

The invention discloses a signal transmission circuit and communication equipment. The signal transmission circuit comprises a first FPGA (Field Programmable Gate Array) unit, a second FPGA unit, a first CPU (Central Processing Unit) and a second CPU, wherein the first FPGA unit comprises a first differential port; the second FPGA unit comprises a second differential port; the first differential port is electrically connected with the second differential port; the first FPGA unit and the second FPGA unit configure the first differential port and the second differential port into single-end ports respectively; and the first FPGA unit acquires in-place state information of the first CPU, transmits the in-place state information to the second FPGA unit, and transmits the in-place state information to the second CPU to finish in-place state detection. According to the technical scheme, a single-end signal is transmitted through a differential circuit, so that the number of signal transmission channels is increased.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a signal transmission circuit and communication equipment. Background technique [0002] In the current signal transmission circuit based on FPGA (Field-Programmable Gate Array, Field Programmable Gate Array), differential signals and single-ended signals need differential circuits and single-ended circuits for transmission respectively, and the two cannot be mixed with each other. Once the circuit is finalized, it can only transmit signals according to the specified requirements. [0003] refer to figure 1 , figure 1 It is a schematic diagram of the existing differential transmission line. In some application scenarios where port resources are relatively tight and only simple single-ended signals need to be transmitted, the circuit can only be re-planned and modified, which is very inconvenient. Contents of the invention [0004] The main purpose of the present invent...
