PI2PCIE212
1.8V, PCI Express Compliant, 2 Differential Channel,
2:1 Mux/DeMux Switch w/ Single Enable
Description
Pericom Semiconductor’s PI2PCIE212 is a 4 to 2 differential
channel multiplexer/demultiplexer switch. The PI2PCIE family
of switch solutions is fully compliant with PCI-express signals
at 2.5Gbps. PI2PCIE212 can switch PCI-express signals up to
a maximum length of 16 inches. Due to its low bit-to-bit skew,
high channel-to-channel noise isolation and high bandwidth, this
product is ideal for PCI Express switching.
Application
Switch a PCI-Express lane output between two PCI-Express lane
inputs
