[SI-LIST] Re: Non monotonicity in daisy chain topology

Hi Vani,
   I have fixed issues like this in the past by slowing down the edge
rate of the driver.  Depending on your timing margin, sometimes a simple
RC network at the driver will do the trick.  It works well for SMBus.

Good luck,
Mike

Subject: [SI-LIST] Non monotonicity in daisy chain topology



Hi,

I observed an inevitable non monotonic behaviour in the devices which
come first in the daisy chain after the driver.
The subsequent devices see reduced effects of non monotonicity, the end
device with a 10k pull down termination seems to be faring well in terms
of signal quality. How to mitigate this behaviour, Kindly suggest some
solutions.

I referred to si-list back mails which has one such discussion on this
issue, it states that it is a known behaviour of devices in daisy chain
topology. But I could not find a solution to change this behaviour.
Please advice.

Thanks and warm regards
Vani
