Abstract
Disclosed are an automotive Ethernet circuit board and communications system, and a vehicle. The automotive Ethernet circuit board includes: a component placement layer, configured to carry a PHY chip and a control chip of the PHY chip; a plurality of signal wiring layers, configured to carry signal wiring between components in the component placement layer; and a signal shielding layer, located between the plurality of signal wiring layers and configured to prevent interference of a clock signal in the signal wiring. In the embodiments of the present application, a plurality of signal wiring layers are used for signal wiring between components, and a plurality of complete signal shielding layers are used to prevent interference of a clock signal in the wiring. The embodiments help reduce signal crosstalk between PCBs, prevent interference of a clock signal in signal wiring, and improve stability and consistency of a data communications system.
