[SI-LIST] Re: jitter introduced by a mated connector

Keith:

The jitter introduced by the connector will be what is called deterministic
jitter which is bit pattern dependent. Do you have access to any version of
spice? You can get a pretty good idea of this jitter by running a bit
sequence through the single line connector model (obtained from your
connector vendor). Cross-talk will also add to your jitter but the
simulation gets more complicated.

Can some point me in the right direction regarding
the min/max jitter introduced by connectors within
a backplane system ??

- I'm looking into GBit Ethernet type
signals and wondering how many passes through connectors
The system can withstand.. .... I know this is a tough question...
I don't mind learning some new math tricks...Assume that
the signals of interest are diff-pairs / FR4 , etc...18" between
connectors (max)...

Does anyone have any experience with Diff pair signal integrity
using a QualitySemiconductor / quickswitch and passing GB diff
pair signals thru this type of device?

feel free to email me direct, if you want.


Thanks,
