I am designing a multi-phase inverter and plan to use multiple of ADuM 5020/5028 to power multiple of ADuM 7701 to measure the in-line phase currents. I am concerned if there will be beat frequency issue when using multiple ADuM 5020/5028. I got this concern as I was comparing ADuM 5020/5028 with alternative devices that provide synchronization capability to prevent potential beat frequency. I read through the datasheet of ADuM 5020/5028 but could not find information about beat frequency. I will appreciate it if you could address this question/concern.
