Figure 10 shows the measurement circuit used to quantify the crosstalk effect in a classical digital appli-

cation.

Figure 11 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

performed with falling edges gives the results within the same range.

5. APPLICATION EXAMPLE
