Webor bit-length is the reciprocal value of the signaling rate; therefore, the time a logic state is valid is simply the UI minus the jitter. Percent jitter, which is the jitter time divided by the time of the UI and multiplied by 100, is more commonly used.

"WebThe number of time quanta per bit (known as the bit time) can range from 8 to 25. There is no analytic formula for determining the optimum bit time in advance, so the calculator tries all of them. The closest integral baud rate prescaler is calculated for each value. The BRP and Tq/bit values are then used to calculate the actual sampling bit rate. " - Ecu transmitter bit timing tolerance
