Description
Pericom semiconductor’s PI3PCIE3242 is a differential exchange
switch featuring pass-through pinout. It supports one full PCI
Express® lane 2x2 Exchange Switch operating at 8.0Gbps PCIe®
3.0 performance.
With the select control input low, Port A connects to Port B, and
Port C connects to port D for an 8-channel differential pass-
though. When the select control input is high Port A connects
to Port D, and Port B connects to Port C.
