Abstract

See full text

A clock system includes a provisioning layer corresponding to a plurality of input clocks, and a plurality of layers arranged according to a hierarchy. The first layer in the hierarchy is operable to arrange the input clocks into groups and for each group select a corresponding group output clock. The remaining layers in the hierarchy are operable to arrange the group output clocks from a next layer higher in the hierarchy into groups and for each group select a corresponding group output clock. The lowest layer in the hierarchy is operable to select one of the group output clocks from the next layer higher in the hierarchy as a selected clock.
