2- Digital Crosstalk

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 signal from 0 to 5V and rise time of 10 ns, the impact on the disturbed line is less

than 20mV peak to peak. No data disturbance was noted on the concerned line. The same results were obtained with falling

edges.

3- Analog Crosstalk

Figure A10 gives the measurement circuit for the analog application. In figure A11, the curve shows the effect of cell 1/24

on cell 2/23, no difference was found with other couples of adjacent cells. In usual frequency range of analog signals (up to

100MHz) the effect on disturbed line is less than -32 dBm.
