4 Crosstalk behavior

7/12

IMPORTANT:

A main precaution to take is to put the protection device closer to the disturbance source

(generally the connector).

Note:

The measurements have been done with the DVIULC6-4SC6 in open circuit.

Crosstalk behavior

4.1

Crosstalk phenomena

Figure 11. Crosstalk phenomena

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

β12 or

β21) increases when the gap across lines decreases, particularly in silicon dice. In the example

above the expected signal on load RL2 is α2VG2, in fact the real voltage at this point has got an

extra value

β21VG1. This part of the VG1 signal represents the effect of the crosstalk

phenomenon of the line 1 on the line 2. This phenomenon has to be taken into account when
