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 to +/-4k V contact ESD protection. In addition to switching, the product also integrates a monitor detection feature. The monitor detection feature works independently on each of the two outputs and allows automatic switching as well as a self generated HPD signal that lets the system know when a monitor is connected or disconnected.
