Description
Pericom’s PI3V712-A is a 7-channel video mux/demux used
to switch between multiple VGA sources or end points. 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~1.0GHz,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8kVofcontactESDprotection.
Application
RoutingVGAsignalswithlowsignalattenuationandhighESD
protection.
