Patent ID: 11870603
Assignee: NXP B.V.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 5:
6. The CAN system of claim 1, where the first and second dual mode bus termination circuits each comprise:
first and second resistors connected in series between the first and second bus wires of the network bus, where each of the first and second resistors has a first resistance value that matches an impedance of the network bus when operating in the differential communication mode;
a splitting capacitor connected between a reference voltage terminal and a shared node of the first and second resistors; and
a third resistor connected between the first and second bus wires of the network bus, wherein the first, second, and third resistors are jointly configured such that the third resistor has a resistance value, when combined with the first and second resistors, that matches an impedance of the network bus when operating in the single-ended communication mode.
