PI3DBS12412A
3.3V, 10-12Gbps 2-Lane 2:1 Mux/De-Mux Switch
Pericom Semiconductor’s PI3DBS12412A is an 8 to 4
differential channel multiplexer/demultiplexer switch.
This solution can switch multiple signal types up to data rate
of 12Gbps. Using a unique design technique, Pericom has
been able to minimize the impedance of the switch such
that the attenuation observed through the switch is minimal.
The unique design technique also offers a layout targeted for
Thunderbolt & SAS 3.0 signals, which minimizes the channel
to channel skew as well as channel to channel crosstalk as
required by high speed signals.
