Data switch and data transmission system

Abstract

The invention provides a data switch and a data transmission system. The data switch comprises at least two switch units and a signal leakage unit; the switch unit is used for controlling signals sentby a transceiving circuit of one channel of a host, sending the signals to the transceiving circuit of one channel of the two channels of the equipment, and controlling signals sent by the transceiving circuit of one channel of the two channels of the equipment to be sent to the transceiving circuit of one channel of the host; and the signal leakage unit is used for transmitting signals of the first switch unit to the first transceiving circuit, and leaks signals at the transceiving circuit of the channel of the equipment connected with the second switch unit. Because the signal leakage unittransmits the signal of the first switch unit to the first transceiving circuit, and leaks the signals at the transceiving circuit of the channel of the equipment connected with the second switch unit, a leakage signal caused by parasitic parameters is just offset, and signal crosstalk between the transceiving circuits of different channels is eliminated.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a data switch and a data transmission system. Background technique [0002] In the process of multi-channel data transmission, the circuit that can select any one of them according to the needs is called a data switch, such as multiplexer, demultiplexer and cross-point switch. [0003] In the high-speed data transmission of data switches, the problem of signal crosstalk is particularly prominent, which not only affects the quality of normal data transmission, but also causes bit errors in severe cases. Therefore, designing a data switch with high channel-to-channel isolation is crucial for the application. Contents of the invention [0004] In view of this, the present application provides a data switch and a data transmission system for eliminating signal crosstalk between channels. [0005] In order to achieve the above object, the application provides the fol...
