Abstract
A transceiver to communicate in a vehicle via a single twisted-pair Ethernet cable includes a transmitter and a receiver, an analog front end, an equalizer, and a controller. The transmitter transmits signals via the single twisted-pair Ethernet cable. The receiver receives signals via the single twisted-pair Ethernet cable. The analog front end receives a first signal received by the transceiver via the single twisted-pair Ethernet cable and outputs a second signal. The equalizer includes a notch filter to cancel electromagnetic interference from the second signal. The controller makes a frequency response of the equalizer independent of the electromagnetic interference by controlling tap values of the notch filter. The controller controls gain of one or more of the analog front end and the equalizer based on the frequency response of the equalizer.
