Description

Technical Field

[0001] The utility model relates to the technical field of electronic communication, and specifically relates to an improved XP_Link interface signal communication device. Background Art

[0002] In the current technical field of electronic communication, as a key component for realizing efficient data transmission, the performance and stability of the XP_Link interface signal communication device directly affect the efficiency and reliability of the entire communication system. However, as Figure 1 shown, there are obvious limitations in the circuit design of the XP_Link1.0 interface signal communication device in the prior art. Specifically, the traditional XP_Link1.0 interface signal communication device usually only has one power access switch. With this design, the XP_Link1.0 interface signal communication device can only monitor a relatively single voltage value and cannot comprehensively reflect the complex state changes during the communication process. For example, in a scenario where multiple chips (such as A and B) are simultaneously involved in XP_Link communication, each chip may require different power support under different workloads. Moreover, the traditional XP_Link1.0 interface signal communication device needs to set resistors on the Link, which greatly affects the stability of the signals on the Link.

[0017] The following will describe in detail the embodiments of the technical solutions of the present utility model with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0018] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present utility model belongs.

[0019] Such as Figure 2As shown in the figure, the present utility model provides an improved XP_Link interface signal communication device, including: a first power access switch for accessing power supply A; a second power access switch for accessing power supply B, where I1 = k * I2, I1 is the current value provided by power supply A, I2 is the current value provided by power supply B, and k is a proportional parameter; a voltage detection unit, which is respectively connected to the first power access switch and the second power access switch, and is used to monitor the voltage values accessed by XPI and XPO in real time, where XPI is the peer end participating in communication and XPO is the local end participating in communication; among them, the first power access switch, the second power access switch, and the voltage detection unit are respectively connected to the Link communication bus.

[0020] In this embodiment, a resistor C is further included, which is arranged inside the communication device. The resistor C is N * M, where N is determined according to the number of communication ends participating, and M is a fixed value. The resistor C is respectively connected to the first power access switch, the second power access switch, the voltage detection unit, and the ground terminal, playing an important role in optimizing the circuit layout, improving the anti-interference ability, and ensuring the communication stability.

[0021] It should be noted that M is determined according to the external resistor value, and the external resistor value can be any value. Therefore, M can also be any value and is not limited in this embodiment.

[0022] During communication, several devices with the same structure are connected together through Link. In order to avoid setting external resistors on the bus, this embodiment sets internal resistors and adopts the method of parallel connection of internal resistors, so that the resistance values of several parallel internal resistors are equivalent to the external resistor value.

[0023] In some embodiments, when the external resistor is 10KΩ, the resistance value of the internal resistor is N * 10KΩ. Specifically, the calculation formula for the equivalent process of the external resistor and the parallel internal resistor is:

[0024] 10K = (N * 10K * N * 10K) / (N * 10K + N * 10K), where N ≥ 2 and N is a positive integer.

[0025] Exemplarily, N = 2. At this time, 400K 2 / 40K = 10K, that is, the parallel internal resistor is equivalent to the resistor set outside the bus.

[0026] In this embodiment, the power supply A is 60uA, the power supply B is 30uA, and k is 2. By accessing different power supplies, it provides a basis for different signal state representations.

[0027] In this embodiment, the physical quantities on the Link communication bus include but are not limited to current, voltage, and power.

[0028] Specifically, when the communication device is started, the first power access switch and the second power access switch can be accessed simultaneously, neither can be accessed, or only one can be accessed. The voltage detection values of this section and the peer end are determined according to the access situation, and the communication state is intelligently controlled according to the voltage detection values.

[0029] In this embodiment, by introducing the second power access switch and optimizing the design of resistor C, the stability and multi-state representation ability of the XP_Link interface signal communication device are significantly improved. In addition, the dynamic resistance value design of resistor C also provides better circuit protection and anti-interference ability for the communication device, further improving the overall performance of the device.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
