Abstract
The invention relates to a 6.25Gbps coaxial structure differential data cable assembly for aerospace. The high-speed data cable assembly includes a micro-rectangular coaxial connector, a micro-coaxial cable, a wave-proof sleeve, a nylon sheath, a heat-shrinkable sleeve and the like. Generally, differential signals are transmitted by twisted-pair differential cables, but when twisted-pair differential cables are used for high-speed signal transmission, the high-frequency attenuation is relatively large, and the signal anti-interference ability is weak, which is not suitable for long-distance use. The high-speed data cable assembly of the present invention uses 2-way 50Ω impedance micro-coaxial cable realizes the transmission of 6.25Gbps differential high-speed signal. It has the characteristics of low high-frequency loss, small delay, strong anti-interference ability and high reliability. It is widely recognized by aerospace models and has been used in aerospace models. Applied in the scoring system.
Description
technical field [0001] The invention relates to a 6.25Gbps coaxial structure high-speed differential data cable assembly used for serial data transmission in the aerospace environment, and belongs to the technical field of high-speed cable assemblies. Background technique [0002] The invention relates to a high-speed serial data transmission protocol TLK3118. TLK3118 is a G-bit-level serial transceiver introduced by TI, which is suitable for an ultra-high-speed bidirectional point-to-point data transmission system. It has the advantages of high transmission rate, simple interface and strong anti-interference ability. It has been gradually applied to the aerospace model data transmission system to achieve high-speed transmission of massive data. The transmission rate of TLK3118 protocol can reach up to 6.25Gbps. At present, engineering applications have been gradually realized in China. [0003] When the traditional twisted-pair differential cable is used for high-speed sig...
