Description
The PI3PCIE3242A 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.
