Fig. A5: Crosstalk phenomenon

The crosstalk phenomena are due to the coupling between 2 lines. Coupling factors (

β12 or β21 ) increase

when the gap across lines decreases, particularly in silicon dice. In the example above, the expected

phenomenon has to be taken into account when the drivers impose fast digital data or high frequency

analog signals. The perturbed line will be more affected if it works with low voltage signal or high load

impedance (few k

Ω)
