Hi all, We have a design where 500Hz signals are traveling from external sensor to the board; in the vicinity of the 500Hz signals, high frequency signals and digitals sections are present. So I am concerned with the signal quality( Crosstalk), is there any possibility that 500Hz signals get affected due to the nearby high frequency signals. Do I need to do SI analysis on that board to know the crosstalk, or any articles or theoretical analysis is sufficient to know the crosstalk and any guidelines in the PCB layout will work? Please help me. Thanks in advance[Umamaheswar U-TLS,Chennai] .
