Crosstalk behavior
Crosstalk phenomena
Figure 13. Crosstalk phenomena
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
example in
point has got an extra value
crosstalk phenomenon of line 1 on 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 disturbed line will be more affected if it works with low voltage signal or high load
impedance (few k ). The following sections give the value of both digital and analog
crosstalk.
