Description

A single clock source should not be used to drive multiple clock inputs for a high-performance processor device: such as multicore ARM Cortex-A15 based 66AK2Ex and AM5K2Ex processors: since excessive loading: reflections: and noise will negatively impact performance. These can be avoided through the use of a differential clock tree instead of a single clock source. This design demonstrates clock generation for the 66AK2Ex and AM5K2Ex families of KeyStone II ARM A15 + DSP and ARM-only multicore processors by use of a differential clock tree. This design shows a complete clock tree resulting in generation of all clocks needed for SoC cores and interfaces.
