4. CROSSTALK BEHAVIOR
Figure 7: Crosstalk phenomena
The crosstalk phenomena is due to the coupling between 2 lines. The coupling factor ( 12 or 21 )
increases when the gap across lines decreases, this is the reason why we provide crosstalk
measurements for monolithic device to guarantee negligeable crosstalk between the lines. In the example
above the expected signal on load R
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 ).
Figure 8: Analog Crosstalk measurements
configuration
Figure 8 gives the measurement circuit for the analog crosstalk application. In figure 9, the curve shows
the effect of the Data line on the CLK line. In usual frequency range of analog signals (up to 100MHz) the
effect on disturbed line is less than -37dB.
