3.3V, 5-differential Channel LVDS
Switch Targeted for 24bit Displays
Description
Pericom’s PI3LVD512 is a 5-differential channel LVDS mux/
demux used to switch between multiple LVDS 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 of870MHz, 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 V_DD and GND that will support up to 12kV of ESD
HBM protection.
