Transmit-receive device, transmit-receive system and transmit-receive information method

Abstract

The invention discloses a transceiver device, which includes a logical device unit and an Ethernet physical layer device: one end of the logical device unit transmits and receives low-speed parallel signals between communication devices, and one end is interconnected to the Ethernet physical layer device to transmit high-speed Parallel signals, and complete the mutual conversion of the low-speed parallel signals and the high-speed parallel signals; the Ethernet physical layer device is used to convert the high-speed parallel signals and standard Ethernet physical layer signals, and through its Ethernet The physical layer interface sends and receives the Ethernet physical layer signal. The invention also discloses a transceiver system, which includes at least two transceiver devices, and the Ethernet physical layer interfaces of the transceiver devices are interconnected through a transmission medium. The invention also discloses a method for sending and receiving information, using the device to complete the sending and receiving of information. By applying the invention, common standard instruments can be used for testing, and devices from any manufacturers can be selected, thereby effectively reducing costs.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a sending and receiving device, a sending and receiving system and a method for sending and receiving information. Background technique [0002] Existing communication devices often have interconnection requirements, and the demand for information flow is also increasing. The traditional interconnection method is gradually being replaced by the serial-parallel converter (SERDES) for interconnection technology. [0003] SERDES is the abbreviation of serializer (Serializer) / deserializer (DESerializer). The interconnection technology using SERDES is a time-division multiplexing (TDM), point-to-point communication technology, that is, multiple low-speed parallel signals at the sending end It is converted into a high-speed serial signal, passes through the transmission medium, and finally converts the high-speed serial signal into a low-speed parallel signal at the receiving end.

Problems solved by technology

[0006] However, since each SERDES driver manufacturer adopts different standards to produce SERDES drivers, and the interfaces of SERDES drivers also use their own private interfaces, the SERDES drivers shipped by different manufacturers cannot be interconnected. An interconnected system Only one company's SERDES driver can be used inside, even if the system is upgraded in the future, it cannot be replaced with another company's SERDES driver

[0007] At the same time, because the interfaces of SERDES drivers are all private interfaces, the interfaces of SERDES drivers produced by different manufacturers must use different test instruments, and standard instruments cannot be used for testing. The longest distance is only a dozen meters, which cannot meet the transmission needs of longer distances

[0008] Furthermore, the SERDES driver has very high requirements for twisted pairs, and ordinary standard twisted pairs cannot meet its requirements, and special interconnected twisted pairs are required, which is costly
