A driver assistance system includes a first camera, a second camera, a first serial interface circuit, a second serial interface circuit, and a hub interface circuit. The first serial interface circuit is coupled to the first camera. The second serial interface circuit is coupled to the second camera. The hub interface circuit is coupled to the first serial interface circuit and the second serial interface circuit. The hub interface circuit is configured to receive transmissions from the first serial interface circuit and the second serial interface circuit, and to transmit control information to the first serial interface circuit and the second serial interface circuit. The hub interface is also configured to encode a clock signal in the control information.
