PI3PCIE3412
3.3V, PCI Express
®
3.0, 8.0Gbps, 2-Lane (4-Channel), 2:1 Mux/DeMux Switch
Pericom Semiconductor’s PI3PCIE3412 is an 8 to 4 differential
channel multiplexer/demultiplexer switch. This solution can
switch 2 full PCI Express
®
3.0 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 minimal. 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 specification.
