Problems solved by technology

[0003] In order to ensure that the signal repeater can accurately retime and regenerate the signal, the setting value of the signal repeater must be adjusted to match the parameters of the signal transmission protocol. If the setting value of the signal repeater does not match the signal transmission protocol, it will Can cause erroneous changes in the frequency or amplitude of the signal, resulting in severe distortion of the signal quality
For example, in a system using the SAS (Serial Attached SCSI) protocol, the setting value of the signal repeater must be adjusted to match the parameters of the SAS protocol, while in a system using the PCIe (Peripheral Component Interface Express) protocol, the signal repeater The set value must be adjusted to match the parameters of the PCIe protocol. Any set value that does not match the signal transmission protocol will make the signal repeater unable to accurately retime and regenerate the signal.
[0004] However, in the existing design, in a system using multiple signal transmission protocols, it is necessary to customize a matching signal transponder for each signal transmission protocol, which is very unfavorable to the design and use of the communication system

Embodiment Construction

[0027] see figure 1 , the figure schematically shows a signal repeater according to an embodiment of the present invention, the signal repeater includes a signal conditioner 10 , a memory 20 and a baseboard management controller (Baseboard Management Controller) 30 . The signal conditioner 10 passes through the I 2 The C (Inter-Integrated Circuit) bus is connected to the memory 20, and the memory 20 is connected to the 2 The C bus is connected to the baseboard management controller 30 . I 2 The C bus includes two serial lines, the serial data line (SDA) and the serial clock line (SCL). 2 The C bus is widely used in the monitoring field of servers because of its few interface lines, simple control methods, small device packaging, and high communication speed.

[0028] The baseboard management controller 30 is a controller embedded on the mainboard of the server, which can operate independently and provide management interfaces in terms of safe remote restart, safe power-on,...

Abstract

The invention relates to a signal retransmission device, which comprises a signal regulation device, a storage and a base plate management controller, wherein the signal regulation device receives a signal from a transmission device, retimes and regenerates the received signal, and transmits the regenerated signal to a receiving device; the signal regulation device and the base plate management controller are respectively connected with the storage; the base plate management controller writes a set value matched with a signal transmission protocol into the storage; the signal regulation device reads the set value from the storage and applies the set value. The invention also discloses a signal retransmission method.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a signal transponder and a signal transponder method. Background technique [0002] In the process of high-speed signal transmission, due to the influence of transmission line noise and the limitation of the driving capability of the upstream chip, the digital signal or analog signal carrying information can only transmit a limited distance. If the transmission distance is too long, the signal strength will be severely attenuated and the signal will be damaged. Severe distortion of quality. To solve this problem, existing designs use one or more transponders to split the transmission line into two or more segments, the transponders retime and regenerate the received signal, and then transmit the regenerated signal to the receiving device Or the next section of the line, in this way, the signal transponder realizes the effective transmission of the signal in the long-dista...
