Tool/software:

Hello Experts,

In case we use two AM263P4 on the same board and communicate each other via FSI, do we need isolation device between them?

Best regards,
Ken

    Hi Ken,

    If the two devices share the same power plane and ground plane of the PCB, the isolation is not required. The isolation device can add large delay on the signals and add skew between the FSI signals.
