Figure A8 shows the measurement circuit used to quantify the crosstalk effect in a classical digital
application.
Figure A9 shows that in such a condition, the impact on the disturbed line is less than 5 mV peak to peak.
No data disturbance was noted on the concerned line. The measurements performed with falling edges
give an impact within the same range.
