How to recover the clock frequency of the CAN bus, CAN bus driver, and, CAN bus system for restoring the clock frequency of the CAN bus for restoring the clock frequency of the CAN bus

摘要

How to recover the clock frequency of the CAN bus, CAN bus driver, and, the present invention provides a CAN bus system for restoring the clock frequency of the CAN bus for restoring the clock frequency of the CAN bus. A master device having a clock frequency generator for providing a clock frequency, CAN bus, connects the slave device at least one. At that time, the slave device, a phase-locked loop that utilizes the predetermined bit pattern as the reference signal is used. The predetermined bit pattern is extracted from the frame transmitted over the bus system by the master device. [Selection] Figure Figure 1
