Abstract:
A transceiver includes a driver stage and a transient-triggered ring suppression circuit. The driver stage has a first transistor coupled between a supply voltage terminal and a first bus terminal and a second transistor coupled between a ground and a second bus terminal. The transient-triggered ring suppression circuit is coupled to the first and second transistors. The transient-triggered ring suppression circuit is configured to be enabled upon transition of the transceiver from a dominant state to a recessive state. Further, while the transceiver is in the recessive state, the transient-triggered ring suppression circuit is configured to attenuate ringing on at least one of the first or second bus terminals.
