Abstract
In one embodiment, a clock generation system comprises first and second hot-swappable oscillator (HSO) devices that generate respective timing signals, a plurality of controllable attenuators for controllably attenuating one of the timing signals, a combiner for combining the timing signals, a redundant clock source (RCS) device for generating at least one clock for distribution to other circuits using an output of the combiner, and logic for switching which of the timing signals is attenuated in response to failure of one of the first and second HSO devices.
