The invention relates to a vehicle-mounted high-speed transmission circuit, a serializer/deserializer including the same and a method of using the same. The transmission circuit includes: a main transmitter for transmitting a first forward signal; the copy transmitter is connected to the main transmitter in parallel, and the copy transmitter is used for transmitting a second forward signal; the pre-driver is located at the upstream of the main transmitter and the replica transmitter, and the pre-driver is used for driving the main transmitter and the replica transmitter to transmit a first forward signal and a second forward signal respectively; and a signal separation circuit connecting the replica transmitter and the main transmitter, the signal separation circuit for separating the reverse signal by the first forward signal. On the basis that low power consumption is achieved, the vehicle-mounted high-speed transmitting circuit supports reverse link transmission of single-end, common-mode and differential signals at the same time, and the development requirement of the data transmission technology in the field of automobile communication is met.
