Product Description

The 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, Diodes has been able to minimize the impedance of the switch such that the attenuation observed through the switch is mininal. 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. PI3PCIE3412 can also be used for application up to 12Gbps.
