A redundant clock distribution system with spread spectrum. In one embodiment, a clock board includes a clock synthesizer configured to provide an input clock signal, and a spread spectrum unit coupled to receive the input clock signal. The spread spectrum unit is configured to frequency modulate the input clock signal, thereby producing an output clock signal wherein energy of the output clock signal is spread over a range of frequencies.
