Abstract
A spectrum spreader may include a signal conductor and a tunable filter. The signal conductor may be configured to receive a clock signal having a clock signal frequency. The tunable filter may be coupled to the signal conductor wherein the tunable filter is configured to spread a frequency of the clock signal responsive to a control signal to provide a spread spectrum clock signal. More particularly, a frequency of the spread spectrum clock signal may be spread relative to the clock frequency. Related communications devices and methods are also discussed.
