Truth Table
Description
Pericom semiconductor’s PI3PCIE3422 is an 8 to 4 channel
differential multiplexer/demultiplexer featuring 8-channel pass-
through. 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 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.
