Description
Pericom Semiconductor’s PI3PCIE2415 is an 8 to 4 differential
channel multiplexer/demultiplexer switch. This solution can
switch 2 full PCI Express® 2.0, 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 specifica-
tion.
Application
Routing of PCIe® 2.0, signals with low signal attenuation.
