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® 2.0 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.
