1. A method for distributing a timing signal to a device, said method comprising:
- receiving a timing signal from a timing source;
receiving a power signal;
superimposing the timing signal on the power signal to facilitate creating a different power signal to be distributed to the device;
decoding the timing signal from the power signal within the device; and
adjusting an internal clock of the device to facilitate synchronizing the internal clock with the decoded timing signal.

Abstract
A method for distributing a timing signal to a device. The method includes receiving a timing signal from a timing source, receiving a power signal, superimposing the timing signal on the power signal to facilitate creating a different power signal to be distributed to the device, decoding the timing signal from the power signal within the device, and adjusting an internal clock of the device to facilitate synchronizing the internal clock with the decoded timing signal.
