Abstract
The invention provides an impedance conversion device for a vehicle-mounted gigabit Ethernet chip adaptive to a coaxial cable transmission, and relates to the technical field of Ethernet communication. The impedance conversion device has a first impedance loop, a cable wiring end of the first impedance loop is connected with the coaxial cable, and a chip wiring end of the first impedance loop is connected with a first signal output end of the vehicle-mounted Ethernet chip; a first chip resistor is connected between a first signal input end and the first signal output end of the vehicle-mounted Ethernet chip, and the sum of an impedance value of the first impedance loop and a resistance value of the first chip resistor is equal to an equivalent resistance value of the coaxial cable.
