Embodiment 1

[0078] like image 3 As shown, the shape of the cross section of the data transmission cable 30 perpendicular to the length direction is flat, and the data transmission cable 30 includes a plurality of signal lines and power lines 303; On the cross section perpendicular to the length direction, they are arranged along the first direction; the plurality of signal lines and power lines 303 extend along the length direction of the data transmission cable 30 . The plurality of signal lines include a first differential pair 301 , a control signal line 302 and a clock signal line 304 . The data transmission cable 30 further includes a second medium filling layer 305 filled between the plurality of signal lines and between the plurality of signal lines and the power line 303, and wraps the plurality of signal lines and power lines in turn from the inside to the outside 303 and the second conductor shielding layer 306 and insulating protective layer 307 of the second dielectric filli...

Embodiment 2

[0124] The main difference between the second embodiment and the first embodiment is that the first embodiment includes one differential pair, namely the first differential pair 301, and the second embodiment includes two types of differential pairs, namely the first differential pair 301 and the second differential pair. A differential pair 301 and a second differential pair transmit signals in different directions.

[0125] like Image 6 As shown, the shape of the cross section of the data transmission cable 30 perpendicular to the length direction is flat, and the data transmission cable 30 includes a plurality of signal lines and power lines 303; On the cross section perpendicular to the length direction, they are arranged along the first direction; the plurality of signal lines and power lines 303 extend along the length direction of the data transmission cable 30 . The plurality of signal lines include a first differential pair 301 , a second differential pair 310 , a c...

Embodiment 3

[0160] like Figure 11 As shown, the electronic system 100 provided by the embodiment of the present application includes a first chip 10 , a second chip 20 , a data transmission cable 30 , a first printed circuit board 40 and a second printed circuit board 50 . The first end of the data transmission cable 30 is electrically connected to the first printed circuit board 40 by welding; the first interface 101 of the first chip 10 is electrically connected to the first printed circuit board 40 by welding, thereby realizing the data transmission cable The first end of 30 is electrically connected to the first interface 101 .

Description

technical field [0001] The present application relates to the technical field of electronic equipment accessories, and in particular, to a data transmission cable and an electronic system. Background technique [0002] At present, the following two ways are usually used to realize interconnection between chips. The first way, such as Figure 1a As shown, the first chip and the second chip are interconnected through a printed circuit board (PCB), a board-to-board (BTB) connector and an FPC (flexible printed circuit). The specific connection relationship is as Figure 1a As shown, the first end of the BTB connector is electrically connected to the PCB, the second end of the BTB connector is electrically connected to the FPC, the first interface of the first chip is electrically connected to the PCB, and the second interface of the second chip is electrically connected to the FPC , and finally realize the interconnection of the first chip and the second chip. The second way, ...
