Abstract
A method for synchronizing a data signal in a bus environment is suggested, the method may include providing multiple clock phases based on a reference oscillator; determining a phase out of the multiple clock phases for a transition of a data signal; and synchronizing the data signal based on the phase determined.
Claims17
A method for synchronizing a data signal in a bus environment, the method comprising:
- providing multiple clock phases based on a reference oscillator, wherein a frequency of the references oscillator is 20 MHz or below;
- selecting a phase from the multiple clock phases for a transition of a data signal as a sampling phase;
- and
- synchronizing the data signal based on the sampling phase, wherein the data signal is a received message on a controller area network (CAN) bus.
