This implies that bus lengths are limited at given CAN data rates. A CAN system’s propagation delay is calculated as being a signal’s round trip time on the physical bus (tbus), the output driver delay (tdrv), and the input com-parator delay (tcmp). Assuming all nodes in the system have similar component delays, the propagation delay
