Full-duplex transmission and reception circuit, serial circuit chip, electronic device, and vehicle

Abstract

A full-duplex transmission and reception circuit includes a transmission module, a filtering module, and an amplification module, with the transmission module having a current-mode logic architecture. A first terminal of the transmission module is connected to a first terminal of the filtering module, and a second terminal of the transmission module is connected to a second terminal of the filtering module. A third terminal of the filtering module is connected to both a first and a second terminals of the amplification module. The transmission module is configured to transmit a forward high-speed differential signal and receive a reverse low-speed common-mode signal. The filtering module is configured to filter out the forward high-speed differential signal from a mixed signal and transmit the reverse low-speed common-mode signals to the amplification module. The amplification module is configured to amplify the reverse low-speed common-mode signal.
