Fig. A8:
Typical Analog Crosstalk measurement
Figure A7 gives the measurement circuit for the analog crosstalk application. In figure A8, the curve shows
the effect of the Data line on the CLK line. In usual frequency range of analog signals (up to 100MHz) the
effect on disturbed line is less than -37dB.

Digital crosstalk measurements
Figure A9 shows the measurement circuit used to quantify the crosstalk effect in a classical digital applica-
tion.
Figure A10 shows that in such a condition signal from 0 to 5V and rise time of few ns, the impact on the
other line is less than 50mV peak to peak. (Below the logic high threshold voltage).The measurements per-
formed with falling edges gives the results within the same range.
