[SI-LIST] Re: SI analysis on Low frequency signals

Crosstalk depends only on:

*Aggressor signal magnitude
*Aggressor signal spectrum
*Interconnect geometry

Given the levels of your sensor, required resolution and the amplitude 
of the digital aggressors you can determine what noise rejection ratio 
you need and design appropriately.
