STEP 1: Determine minimum permissible time for the … 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.
WebFigure 2. Time Quantum and Bit-timing. Bit-timing is the main issue in determining the bus distance in a CAN system. The basic unit in bit timing is called the Time Quantum, TQ. Each bit segment is comprised of an integer multiple of the TQ.
