0 `描述 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. 特性 Differential clock tree for 66AK2Ex and AM5K2Ex multicore ARM Cortex-A15 SoCs Uses CDCM6208 to generate all clocks needed by SoC and peripherals Uses CDCM6208 EVM Control GUI to generate control register values. Complete system reference with schematics, BOM, design files, and HW Design Guide, implemented on the K2E EVM platform for testing and evaluation.
