Abstract
Integrated circuit (IC) packages with multiple clock sources are disclosed. A disclosed IC package includes a first die having a first clock source and a first clock tree and a second die having a second clock source and a second clock tree. The first clock source and the second clock source may be coupled to the second clock tree and the first clock tree, respectively, through a plurality of interconnects to form a clock tree network on the IC package. The clock tree network may be operable to be driven by either the first clock source or the second clock source.
