Description
Pericom Semiconductorâs PI2PCIE2412 is an 8 to 4 differential
channel multiplexer/demultiplexer switch. This solution can
switch 2 full PCI Express, Gen-II, lanes to one of two locations.
Using a unique design technique, Pericom has been able to
minimize the impedance of the switch such that the attenuation
observed through the switch is negligible. The unique design
technique also offers a layout targeted for PCI Express signals,
which minimizes the channel to channel skew as well as channel
to channel crosstalk as required by the PCI Express speciï¬cation.
Application
Routing of PCI-Express, Gen-II, signals with low signal attenu-
ation.
