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 PCIe lane output between two PCI Express lane inputs.
