... Figure 13. Note: The measurements have been done with the HDMIULC6-4SC6Y in open circuit. IMPORTANT: An important precaution to take is to put the protection device as close as possible to the disturbance source (generally the connector). 3.4 Crosstalk behavior Figure 15. Crosstalk phenomena The crosstalk phenomena is due to the coupling between 2 lines. The coupling factor (β ...
