Abstract: Provided herein is a digital communications bus suitable for automotive applications, along with bus controllers and sensors that use the bus and its associated communication methods. One illustrative sensor includes: a clock signal generator; a bus interface coupled to differential signal conductors to detect periodic synchronization pulses from a bus controller; and a controller that aligns a clock signal from the clock signal generator with the periodic synchronization pulses. The bus interface sends digital data between the periodic synchronization pulses to the bus controller using the clock signal to control symbol transitions.
