Product Description

The PI2PCIE2422 is an 8 to 4 channel differential multiplexer/demultiplexer featuring 8-channel passthrough. It supports two full PCI Express lanes at 5.0Gbps Gen II 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 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.
