  • Method for trimming an adjustable oscillator to match a CAN-bus and a CAN-bus communication controller
    Patent number: 8542069
    Abstract: A method for trimming a cycle time of an adjustable oscillator to match a Controller Area Network-bus (CAN-bus) operating with a predetermined bit time includes determining a measured number of cycles of an adjustable oscillator between a first signal and a second signal within a CAN frame transmitted on a CAN-bus; determining an information about a present cycle time of the adjustable oscillator using the measured number of cycles and a nominal number of cycles per bit time; and trimming a cycle time of an adjustable oscillator to match the CAN-bus operating with a predetermined bit time based on the determined information.
