ABSTRACT:
An apparatus for generating precision time signals includes a source of power line timing information, a source of precision time signals, and a timing circuit. The timing circuit is coupled to the source of precision time signals to receive a precision time signal there from, and is operable to generate clock information based on the precision time signal. The timing circuit is further operable to generate clock information based on the power line timing information.
