Data transmission cable and related device

An electronic device comprising:

• a camera module,
• a device mainboard comprising an image processor, and
• a transmission cable comprising a protective layer and at least two data transmission cables, the protective layer covering the data transmission cables,
• wherein at least one of the data transmission cable comprises:
• a signal bundle comprising at least three signal cables disposed at intervals, pairwise signal cables forming a differential pair signal cable configured to transmit a differential data signal;
• a ground cable encircling and covering the signal bundle, the ground cable configured to transmit a ground signal and isolate the signal bundle from a signal bundle of another data transmission cable;
• and
• a filling medium disposed in space defined by an inner side of the ground cable except the signal cable;
• and
• the camera module is configured to transmit image data to the image processor by using the at least two data transmission cables.

A transmission cable comprising:

• first, second and third signal conductors;
• a first shield surrounding the first, second and third signal conductors;
• a first filler disposed within the first shield to space the first, second and third signal conductors apart from one another;
• fourth, fifth and sixth signal conductors;
• a second shield surrounding the fourth, fifth and sixth signal conductors;
• a second filler disposed within the second shield to space the first, second and third signal conductors apart from one another;
• and
• a protective layer enclosing the first and second shields and at least one further conductor,
• wherein the first and second signal conductors in use convey a first differential signal, the second and third signal conductors in use convey a second differential signal, and the first and third signal conductors in use convey a third differential signal.
