Description
Pericom semiconductor’s PI3PCIE3442 is a differential exchange
switch featuring pass-through pinout. It supports two full PCI
Express® lanes 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.
Application
Switching 4 lanes of DP1.2 from PC/Notebook/Tablet to Display
monitor
