PI2PCIE2212
PCI Express® 2.0, 1-Lane,
2:1 Mux/DeMux Switch w/ Single Enable
Description
Pericom Semiconductor’s PI2PCIE2212 is a 4 to 2 differential,
bi-directional channel multiplexer/demultiplexer switch. Due to
its low bit-to-bit skew, high channel-to-channel noise isolation
and bandwidth, this product is ideal for PCI Express® 2.0 signal
switching at 5.0Gbps.
Application
Switch a PCI Express® lane output between two PCI Express lane
inputs
