Description
Pericom Semiconductor’s PI2PCIE412-D is an 8 to 4 differential channel multiplexer/demultiplexer switch. This solution can switch 2 full PCI Express 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 specification.
Application
Switch a PCI-Express lane output between two PCI Express lane inputs.
