Description
Pericom’s PI3V712-A is a 7-channel video mux/demux used to
switch between multiple VGA sources or end points. In a note-
book 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 ~1.0GHz, the signal integrity will remain strong even through
the long FR4 trace between the notebook and the docking sta-
tion. In addition to high signal performance, the video signals are
also protected against high ESD with integrated diodes to V
DD
and GND that will support up to 8kV of contact ESD protection.
Application
Routing VGA signals with low signal attenuation and high ESD
protection.
