Description
Pericom semiconductor’s PI2PCIE2422 is an 8 to 4 channel
differential multiplexer/demultiplexer featuring 8-channel pass-
through. 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.
