Abstract: A CAN bus system that permits a slave node to be connected to the CAN bus. The slave node uses a preamble of a data frame transmitted by the master node on the bus to generate an internal CAN sampling clock. The slave node over-samples frames transmitted over the bus, and monitors the sampled data for a predetermined pattern, which is used to generate the slave node CAN sampling clock. Thus, the slave node does not require or include an external crystal for generating its CAN sampling clock.
