    Hi everyone,
    It seems a simple question.But I still have something i
    cannot completly understand.

    A daisy chain is often used a mulidrop topology, which need an
    end-termination. And, source-termination doesnot work properly in
    daisy chain,because the device in the middle of the chain would get a
    plateau.
    So, in a design , i should figure out minimul distance between,
    say two receivers. in other words, beyond what distance between two
    receivers , source-termination should not be used, and this topology
    can be named a daisy chain?
