Description

The PI3PCIE3442A 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 passthough. When the select control input is high Port A connects to Port D, and Port B connects to Port C.
