Figure 9.
The measurements have been done with the USBLC6-4SC6 in open circuit.
A good precaution to take is to put the protection device as close as possible to the
disturbance source (generally the connector).
Crosstalk behavior
Crosstalk phenomenon
Figure 11. Crosstalk phenomenon
The crosstalk phenomenon is due to the coupling between 2 lines. The coupling factor ( 12
or 21) increases when the gap across lines decreases, particularly in silicon dice. In the
above example the expected signal on load R
has got an extra value
crosstalk phenomenon of the line 1 on the line 2. This phenomenon has to be taken into
account when the drivers impose fast digital data or high frequency analog signals in the
disturbing line. The perturbed line will be more affected if it works with low voltage signal or
high load impedance (few k ).
