Abstract
A synchronization arrangement for a distributed microcontroller network has a number of distributed microcontrollers each having an internal clock frequency. Each microcontroller transmits data signals via the network. A frequency correction arrangement of each microcontroller is arranged adjust the internal clock frequency, in dependence upon a phase difference between the internal clock frequency and the logic level transitions of the data signals received via the network, such that the clock frequencies of the microcontrollers become phase-synchronized over time.
