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. The Time Quantum is the smallest discrete timing resolution used by a CAN
