A circuit is provide comprising a first input coupled to a transmit data input of a bus transceiver; and a first output coupled to a bus. The circuit is configured to be coupled in parallel with the bus transceiver. The circuit is further configured to, in response to a dominant to recessive transition on the transmit data input, lower an impedance of the bus.

Push pull ringing suppression circuit

A transceiver for sending and receiving data from a controller area network (CAN) bus I disclosed. The transceiver is configured to detect if a node, after losing an arbitration, has sent a dominant bit on the CAN bus. The transceiver further configured to send a predefined bit pattern on the CAN bus after receiving the dominant bit from the node.

CAN transceiver

A circuit is provided for ringing suppression. The circuit comprises a termination resistor coupled to a bus via a switch; and a control circuit. The control circuit comprises an input coupled to a data input pin of a bus transceiver and an output coupled to control the termination resistor. The circuit is configured to selectively couple the resistor to the bus in response to a transition on the input bit stream.
