Subject: [SI-LIST] : crosstalk through resistor networks?
I am interested in using some small-package (QSOP) resistor networks for
terminating a large number of bus-signals in a design. Signal rise-times
range from ~200ps to 1ns or so.
I have found some devices that look suitable here:
I am wondering whether such an approach will have crosstalk problems.
Has anyone analysed this and can give me some advice?
I presume that if traces are suitably separated before and after the
resistor package then the crosstalk induced between adjacent signals
will be reduced. These signals are very close together for the 3mm or so
across the resistor package - is this likely to cause problems?
Thanks for any help,
