Webto choose appropriate value of NBT and bit timing parameters to get the desired bit rate as per the propagation delay and oscillator tolerance requirements. The goal is to equip the engineer with a simplified approach and tool for quick & easy determination of CAN bit time parameters used to program CAN controllers. 2. Propagation delay WebCAN network has its own clock generator, usually a quartz oscillator. The timing parameter of the bit time (i.e. the reciprocal of the bit rate) can be conﬁgured individually for each CAN node, cre-ating a common bit rate even though the CAN nodes’ oscillator periods (fosc) may be different.
