Abstract:
The present application relates to a circuit and a transceiver comprising the circuit. The circuit comprises two bus line terminals for coupling to a bus and a bridge circuit comprising two legs. Each leg comprises an adjustable pull resistance and an adjustable push resistance connected in series with a respective one of the two bus line terminals. The adjustable pull resistances and the adjustable push resistances of the bridge circuit enable to independently adjust a driver impedance and to independently adjust a differential driver voltage on the bus. The circuit may further comprise an edge detector is coupled to a transmit data input and configured to detect a transition on the transmit data input and to adjust the impedances of the adjustable pull resistances and the adjustable push resistances in response to the detected transition.
