Assignee: NXP B.V.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A circuit arrangement for a line termination of a Controller Area Network (CAN) serial bus having a twisted pair of cable wires, the circuit arrangement comprising:
a dual mode bus termination circuit which is connected between signal lines of the serial bus and configured to support both differential and single ended communication modes over the serial bus;
wherein the dual mode bus termination circuit comprises first and second resistance termination paths connected in parallel between first and second bus wires of the serial bus to provide an odd mode termination impedance (RODD) that matches an impedance of the serial bus when operating in the differential communication mode, and to also provide an even mode termination impedance (REVEN) that matches an impedance of the serial bus when operating in the single-ended communication mode.
