It supports two full PCIe® lanes 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 and Port C are in a high-impedance state. The mux/demux function is between Port A and Ports B or D as determined by the select input control.
