Abstract:
A method of distributing clock signals includes receiving a plurality of clock signals into a corresponding plurality of processing blocks; determining frequency offset data between a first clock signal of the plurality of clock signals and each of the other clock signals of the plurality of clock signals; periodically determining phase offset data between the first clock signal and the other clock signals; and transmitting the first clock signal, the frequency offset data, and the phase offset data on a pulse-width modulated clock signal. The method includes receiving a modulated clock signal, the modulated clock signal include a carrier clock signal, a frequency offset data, and a phase offset data on a pulse-width modulated clock signal; and recovering a plurality of clock signals based on the first clock signal, the frequency offset data, and the phase offset data.
