APPLICATION NOTE

Calculator for CAN Bit Timing Parameters

Calculator for CAN Bit Timing Parameters

Controller Area Network (CAN) nodes use user-specified timing parameters to sample the asynchronous bitstream and recover the clock. These parameters are typically based on the frequency of the available reference oscillator. There may be several options available for a given frequency, and some of them will allow a looser oscillator tolerance than others. This application report details the creation of a bit timing calculator to maximize the oscillator tolerance for the CAN modules on TI microcontrollers.
