Description
Pericom semiconductor’s PI3PCIE3452 is an 8 channel differential
matrix swich featuring flexible port control and routing options.
It supports two full PCI Express
performance.
Port A or C can connect to either Port B or Port D, for pass-
through or mux/demux operations in flexible configurations.
Isolation of all ports is also an option.
The PI3PCIE3452 is intended for redundancy applications in
sensor, storage and telecom systems.
