Abstract:
A method for recovering a clock frequency of a CAN bus, the method including: receiving a data signal, wherein the data signal includes at least one state transition; detecting the state transition; and adjusting a frequency of a clocking signal generated by an oscillator circuit, wherein the frequency is adjusted when the state transition is detected and adjusting the frequency is for recovering the clock frequency of the CAN bus.
