Description

Pericom semiconductor’s PI2PCIE2442 is a differential exchange

switch featuring pass-through pinout. It supports two full PCI

Express lanes operating at 5.0Gbps PCIe

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.
