Hi everyone,
It seems a simple question,But I still have something i
cannot completly understand.
A daisy chain is often used in multidrop 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;using source-termination, all load should be at the end of the
line.
So, in a design , i should figure out minimul distance between,
say two receivers. In other words, I should decide beyond what distance
between two
receivers , source-termination should not be used, and this topology
can be named a daisy chain?
Could anyone provide a deeper explanation? Thanks a lot!
