摘要
An Ethernet transceiver and an Ethernet transmission method are disclosed. The transceiver is adapted to detect the level amplitude of a received analog signal, adjust an amplification factor adaptively according to the detecting result to make the level amplitude of the received analog signal which has been amplified reach a same output level amplitude, perform an analog-to-digital conversion and a codec process, and transmit the signal to a MAC layer of the Ethernet. The transceiver is further adapted to amplify the level of a signal to be transmitted to a coax network and output the signal. The amplification factor is determined according to a maximum attenuation loss between coaxial terminals. In the present invention, an interaction between an Ethernet access point and a coaxial terminal and an interaction between coaxial terminals are carried out, which makes the CSMA/CD MAC layer of the Ethernet be adopted in an application environment of radio and television coax network.
