METHOD, CAN BUS DRIVER AND CAN BUS SYSTEM FOR THE RECOVERY OF A CLOCK FREQUENCY OF A CAN BUS

摘要

A method, a CAN bus driver and a CAN bus system for the recovery of a clock frequency of a CAN bus, which couples a master device, that has a clock generator for providing the clock frequency, to at least one slave device. A phase-locked loop is used in the slave device, in this context, which utilizes a predetermined bit pattern, that is extracted from a frame sent by the master device via the bus system, as reference signal.
