Timing synchronization for wired communications
First Claim
1. A first wired communications device comprising:
- a coupling circuit, for coupling to a wired communications medium, configured to receive a spread-spectrum timing-reference signal through the wired communications medium, from a second wired communications device; and
a microcontroller, configured to detect a code-phase of the received spread-spectrum timing-reference signal,wherein the first wired communications device is configured to transmit data to the second wired communications device through the wired communications medium, with a timing that is defined relative to the detected code-phase of the received spread-spectrum timing-reference signal.

Abstract
A wired communications device configured to: receive a spread-spectrum timing-reference signal through a wired communications medium, from a second wired communications device; detect a code-phase of the received timing-reference signal; and transmit data to the second device through the wired communications medium, with a timing that is defined relative to the detected code-phase. Also provided is a master device configured to communicate with the wired communications device. The master device is configured to generate and transmit a spread-spectrum timing-reference signal to one or more first devices, through a wired communications medium and to receive, through the wired communications medium, data transmitted by the one or more first devices.
