1. A sensor that comprises:
a clock signal generator;
a bus interface coupled to differential signal conductors and configured to detect periodic synchronization pulses from a bus controller, each pulse of the periodic synchronization pulses initiating an interval for transmission of a data frame to the bus controller without further data transmission from the bus controller; and
a controller configured to align a clock signal from the clock signal generator with the periodic synchronization pulses,
the bus interface configured to send the data frames between the periodic synchronization pulses to the bus controller and to use the clock signal to control symbol transitions.
