PI3PCIE3412ZHE

New Product Databrief 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.
