Description
Pericom’s PI3LVD400 is a 4-di erential channel high-speed
switch used for LVDS or TMDS signals. e PI3LVD400 can be
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 of 1.7GHz, the signal integrity will remain strong
even through the long FR4 trace between the notebook and the
docking station. e device also o ers the user a secondary path
for DDC signals. is DDC path can be used for both switching
as well as voltage translation from 5V down to 3.3V. 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 12kV of ESD HBM protection.
