In a notebook application where analog video signals are found in both the notebook and the dock, a switch solution is required to switch between the two video port locations. With the high bandwidth of ~1.7GHz, the signal integrity will remain strong even through the long FR4 trace between the notebook and the docking station. In addition to high signal performance, the video signals are also protected against high ESD with integrated diodes to VDD and GND that will support up to12kV HBM ESD protection. Application Routing VGA signals with low signal attenuation and high ESD.
